Veggie Tra-a-a-a-a-ay

My son’s first grade class is putting on a play this evening for the parents. I was asked to bring a veggie tray and since the play is about farm animals, I thought the veggies should get into the spirit. My son is going to be a chicken in the play, but I couldn’t figure out how to make a veggie chicken. Hmmm, are cauliflower sheep vegan?
