Although a stuffed pizza looks the same as a deep-dish pizza on the exterior, there are a variety of differences that affect the taste, texture, and consistency of the dish. Stuffed pizzas are assembled with a large layer of bread or crust with layers of cheese, meat, and vegetables. Like a traditional pie, a stuffed pizza includes an extra layer of dough that is inserted above the meat and cheese. The only difference between a pie and a stuffed crust pizza is the layer of diced tomatoes that are embedded on the second layer of dough. In addition, a stuffed pizza is baked with canola oil rather than corn oil.
