Pizza Casserole tastes like eating pizza but in pasta form, almost like a lasagna. It has ten layers including mozzarella & ricotta cheeses, ground beef, pepperoni, noodles and an amped up spaghetti/pizza sauce. It is absolutely mouthwatering comfort food. This main dish is terrific for company or potlucks since it can serve 15 people. It’s also wonderful reheated for lunches.
