I've made this casserole for several new mommies who can just bake it that day or throw it in the freezer and save it for when they need it. This recipe makes 2 13x9 dishes so eat one tonight and save the other in the freezer.
Preheat oven to 350 degrees. In large skillet heat oil. Add beef, onion and garlic. Add seasoning. Brown and drain. Stir in sauce and 3 cups of cheese (I also like to add extra pepperoni slices as well). Place in 2 greased 13x9 inch dishes. Sprinkle with remaining cheese and pepperoni slices. Bake 25-30 minutes.
