Make the Pizza Hut famous stuffed crust pizza vegan! This vegan stuffed crust pizza recipe is the best vegan pizza I've had yet. The ingredients for this pizza pie include grated vegan cheese, green peppers, veggie pepperoni or sausage, veggie ground round, mushrooms, olive oil, pizza dough, homemade pizza sauce and of course, vegan cheese for the stuffed crust. I also recommend using cornmeal to powder the pizza pan (if you are using one).
