I am a vegetarian and my partner is not. We are doing a southwest theme buffet. I need to give ideas to our caterer about what I would like, but has to be something easily done in a buffet style. Most of his ideas involve everything smothered in cheese and dairy. Pet peeve! I still want it to be healthy and fresh but don't want the typical veggie lasagna. I also want it to be amazing to show people that veggie food can be filling and tasty. Ideas?
