I tried to duplicate a pizza that dh use to have many years ago...double bacon cheeseburger. I sauteed some onions, mushrooms and ground up veggie burgers then added some spices and cheeze on top. I don't think it quite tasted like it use to but actually was not bad. The second pizza had mushrooms, green olives, pineapple and artichoke hearts on it. Definitely better than take out pizza.
