Ooh, soup is good. Make split pea with ham. Load it with root veggies. Very good.
Otherwise, try making one of the tofu pudding things. Just add some green food coloring and a cute little decoration on top.
Make green eggs and ham. I work at a restaurant for breakfast once a week and my boss made green eggs and ham. She made scrambled eggs with some pesto and garlic and a little parm cheese and it was really good! Probably not the easiest to keep warm for a taster session though...
