Cooking with beer for a vegetarian I know, that there are many threads on what you can cook with beer as an ingredient.

But: I recognized that all of them include some sort of meat or fish and I eat neither.

So what am I asking you:

Do you have some ideas on how to use the possibly greatest liquid of all times to cook some awesome (vegetarian or vegan) dishes?

To start I think I found a nice beer-pumpkin soup which ingredients are, besides the obvious beer and pumpkin, butter, onions, vinegar, cream and cress.

EDIT :

To be more clear. I ask you to name me something that you have tried and that you would recommend.
I used this recipe for Black Bean Soup with Roasted Poblano Chiles.  It doesn't include beer as an ingredient but I chose this recipe as part of the beer/food pairing menu I put together for my parents.  I decided to pair it with Out of the Ashes (Smoked Marzen) from Fort Collins Brewery.  I poured about 1 1/2 cups of it into the soup while it was cooking.  You may not be a fan of smoked beers, but it went amazing with this soup.  The smokiness blended with the soup and did not have a strong flavor.
