Of all the side dishes i eat, i would have to say that my favorite is Macaroni and Cheese.
 Macaroni and Cheese is delicious. I love having it with pizza for breakfast. Not very healthy, is it?
You could incorporate other ingredients to make it healthier, like meat and vegetables, but it will still be high in carbs and not good for a diabetic or ketogenic diet.
I see. What is the Ketogenic diet? I have never heard of it.
Ketogenic diet
The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain function. However, if little carbohydrate remains in the diet, the liver converts fat into fatty acids and ketone bodies
Macaroni and cheese
Macaroni and cheese—also called mac and cheese or mac n cheese in American and Canadian English, macaroni cheese in the United Kingdom—is a dish of English origin, consisting of cooked macaroni pasta and a cheese sauce, most commonly cheddar. It can also incorporate other ingredients, such as breadcrumbs, meat and vegetables.
Traditional macaroni and cheese is a casserole baked in the oven; however, it may be prepared in a sauce pan on top of the stove or using a packaged mix.
