This is the exact recipe I used to make when I worked at Pizza Hut in high school. Don't ask when that was! This is great served in individual pasta dishes, but a casserole dish is fine.
large green bell pepper, diced
large onion, diced
ounces margarine, ½ stick
teaspoon garlic powder
pound assorted pasta, wheels, shells, spirals, ziti
pound pepperoni. sliced thin then cut in half
ounces mozzarella cheese, shredded
pound hamburger, browned
pound Italian sausage, browned
(16 ounce) jar meat flavored sauce
Melt margarine over medium high heat in a skillet. Add onions, peppers, and garlic powder. Sauté for about 4 minutes. Meanwhile, cook pasta according to box directions. Heat sauce and combine with cooked hamburger and cooked sausage. Lightly grease a 13 x 11-inch casserole dish or your individual pasta dishes. Place 1/2 of the cooked pasta in the dishes, followed by 1/2 the vegetables, 1/2 of the pepperoni and 1/2 sauce. Repeat another layer. Spread mozzarella cheese over top. Bake at 350 degrees F for about 45 minutes or until cheese is melted.
