I started out with this recipe for a guide, but actually my mother had made something similar in the past.
I made one big one, out of some store bought pizza dough. I used a combination of hot and sweet Italian sausage and waaaay more cheese than the original recipe. I also sauteed 1/2 of a green pepper and 1/2 of a medium onion with my sausage and mushrooms. I was so eager to cut this thing up, that I forgot to take a picture of it after it was baked. I did serve it with pizza sauce; we all loved it.
