I went to a tasting at my wedding venue recently and 90% of the food they had was just not cooked properly. A lot of things were dry, some things were under seasoned, some things were over seasoned. It was a mess. I can't use an outside caterer, but they're open to making whatever I request.
A meat carving station seems like something that would be hard to mess up but still taste good. Maybe slow-cooked chicken stuffed in baked peppers? I'm stumped.
