Pizza pasta pie is a recipe that combines the flavors of pizza and pasta into one dish. The dish is made by layering a pasta dough with a tomato sauce, mozzarella cheese, and pepperoni. The pie is then baked in an oven until the dough is golden brown and the cheese is melted.
Cook spaghetti in boiling salted water till al dente. Immediately drain in a colander. Stir the butter or margarine into the hot spaghetti; stir in the beaten eggs and the 1/3 cup Parmesan cheese. In a greased 10 inch pie plate form the spaghetti mixture into a "crust". Sprinkle shredded mozzarella cheese over the crust.
In a large skillet cook sausage, mushrooms, pepperoni, onion, and garlic till sausage is brown and onion is tender. Drain off fat. Stir in undrained tomatoes, tomato paste, and oregano; heat through.
Turn the meat mixture into the crust. cover the edges with foil. Bake in a 350 degree oven for 20 minutes. Sprinkle with the 2 tablespoons Parmesan cheese. Bake the pie about 5 minutes more or till cheese is melted.
