If we aren't supposed to eat meat, why are we trying to make fake meats that taste like real meat?
I'm not a vegetarian, but my wife is and I try not to eat much meat.
We buy a fair amount of those substitutes. And the reason isn't because we're biologically determined to need meatlike things. It's more because meat textures and flavors are what I was raised on and my notion of accessible recipes and tastes was formed by my culinary upbringing.
I know people raised as vegetarians and from cultures that eat little or no meat, they find fake meat products weird and gross.
Yes, biology has a role in our tastes, but early experience definitely sets them more. Travel around the world and although there are commonalities and things to be enjoyed by anyone, there are textures and flavors most people in one culture love that would be disgusting to most people in another culture.
My wife is Mexican. To her bell peppers just taste weird. Peppers in her experience are supposed to be spicy. It's unnerving for her to eat one with no spice. her whole family feels the same. My mom was raised with classic middle America cuisine. When we try to introduce her to real Mexican food she hates it and will only eat things that resemble Americanized Tex-Mex. >

Nailed it, this should get a delta. What an individual is used to eating during their life  impacts their tastes much more than genetics or whatever we were “designed” to be.
Fake meat is mostly made as a meat substitute for meat eaters. If someone gave me a bag of lentils, I wouldn’t know what the hell to do with it because I never messed with lentils and we never ate them at home. >


If vegetarian/vegan diets were "biologically appropriate," there would be no desire to create and or consume these products

Logically how does that differ from:

If meat eating was intended, there would be no desire to cook or add barbeque sauce to meats for us to eat them?

But that out of the way, who says human's aren't omnivores by nature? >

Hominids have been cooking food since before our species evolved. Homo sapiens appeared 300 thousand years ago, while our ancestors have been cooking for more than double that. Also, barbecue sauce doesn't emulate something else in the same way that fake meat does >

Part of the OP stated:

There is a large body of evidence which I believe proves our "non-herbivorous design" but I'm strictly speaking about the presence of these fake/make-believe animal products and what that tells us about our subconscious design/motivation and biological requirements.

So, I was doing what he suggested, and ignoring all that kind of stuff, and only focusing on the taste/texture angle. >


humans are designed

Humans aren't designed. 

no desire to create and or consume these products.

Marketing exists. 

We have thousands of years of evolutionary history and biological design which drive us to make dietary choices

Explain processes foods then? Explain low calorie sugar rich products? Why aren't we only consuming raw foods found in nature? 

veg/vegan eaters create these "fake" foods because they have an internal, subconscious drive to consume animal products

Or it's profitable...

omnivorous diet.

Vegans don't deny our ancestors ate meat. But in this day and age we can choose to do things differently than our past. >

Too notch response >

Beer is not natural.
When someone craves a cold one on hot day, does that mean people are evolutionarily driven to crave beer?
Plant based “meats” exist because when you’ve been eating meat your whole life, you crave something that is familiar to what you are used to.
Chicken nuggets and hamburgers aren’t natural either, yet there are plant based substitutes that try to emulate those… because people are familiar with those. >

I mean I get what you are saying but humans very much are streamlined for drinking beer, over time we (humans) have developed an alcohol tolerance that puts most animals to shame just based on how our bodies process alcohol. >

Okay, but alcohol is not natural, nor are we evolutionarily driven to crave alcohol. >

Depends on what you mean by evolutionary? Alcohol is enjoyed by more than just humans, and other animals seek out alcohol once they figure out it exists. To sum it up in a meme format.
Humans: evolves consciousness
Humans: "oof, I don't like that"
Humans: invents alcohol
Humans: "that's better" >

We already have proof that we are omnivores. Our teeth are designed for meat and plants. >

Not because vegetarians and vegans often live in households with people who still eat regular meat so having something you can easily swap in for the meat the other people are eating significantly reduces the complexity of making meals while still allowing the vegetarian/vegan person to get the same nutrient intake? >

We eat them in my household because we enjoy the taste and texture of meat but don’t want to support industrialized animal agriculture. >

Most of those products are made for meat eaters trying to cut their meat for moral/environmental reasons, most vegetarians are put off by the meat taste and texture after a long time not eating it. I’ve never met a vegetarian who eats them. >

I am sure others have pointed out this before but I will too:
I agree with your statement but completely disagree with your reasoning.
Humans are in fact omnivores and a healthy and balanced diet includes animal products. A lot of these can be substituted naturally or through modern food science but the fact remains that historically the easiest and best sources of those nutrients were and still are animal products and meat.
But the reason why we have "beyond meat" and other vegetarian / vegan products that are promoted and marketed in a type of language that's reminiscent of meat has nothing to do with human diet itself. These products are marketed this way to sell, not because there is some innate need to consume meat. Where I live these names are not that common and I don't know a single person who "came out" as a vegan only after "beyond meat". If you are vegan you eat the things you eat because they don't contain meat, not because of the name. It doesn't even make any sense when you type it out. 
The reason for this marketing is that there is a crisis of masculinity in America / the West, and perhaps even globally in some aspects. Vegetarianism and Veganism has long been derided in the West as unmanly, as feminine, weak, and as "gay". Vegan men are constantly being made fun of for their choice of diet in the West and their manliness is questioned a lot.A lot of men would not even buy vegan / vegetarian products if their health depended on it or if it wasn't even for them but for a family member or friend because they are terrified of being thought of as "less than manly".
So in order to exploit the purchasing potential of men as well as other benefits to replacing meat products, companies came up with marketing slogans and terms that make their products look and sound "manly". So now that you can't tell the difference between a genuine burger patty and "beyond meat" people feel more encouraged and secure about their choices because now the imaginary people in their head won't laugh at them if they order cauliflower buffalo wings instead of regular buffalo wings. >


My argument/belief is that the widespread existence of fake meat/animal products, recipes, etc is strong evidence that humans are designed to consume meat and animal products (omnivorous diets).

Humans are not designed. Our status as omnivores is not "proved" by meat alternatives. Our status as omnivores is "proved" by the fact that we can eat and digest an omnivorous diet.
What your attempting here is a little sorta gotcha! piece of faulty rehtoric that you can deploy in some jagoff arguement you wanna have with vegans and vegetarians. I would highly encourage you to simply not engage in those sorts arguments at all. >

So, I was vegetarian for a few years. I strongly disagree. Most "fake meat" products I ate were not my favorite. Specifically, I dislike the fake meat veggie burgers. A black bean patty or something with recognizable vegetables was always my favorite. Those were not trying to be burgers (although often marketed as "burgers"), they were just a different warm sandwich. Things you mention like cauliflower wings again do not taste anything like wings - it's just a fun way to eat wing sauce. >

How do you reconcile that with the fact that those products imitate highly processed meat, that in no way appears meat-like or animal-like from an atavistic, primal perspective?
If this is all driven by some kind of lizard brain wiring, wouldn't we crave - above all - sweet nutritious organs such as liver, raw jiggly animal fat, warm blood? Those foods are not only never recreated by vegans, but also hardly popular among meat-eaters.
