Spaghetti Pizza Casserole

This one we had a while ago, but it was really tasty and easy to make. It made quite a bit for leftovers too.

7 oz spaghetti
1/2 c egg substitute or 2 eggs
1/4 c grated Parmesan cheese
1 pound lean ground beef
1 medium onion, chopped
1/2 c chopped sweet yellow pepper

Cook spaghetti. Rinse with cold water and drain. In a bowl, toss spaghetti with eggs and parmesan cheese. Spread evenly into a 15x10" baking pan coated with cooking spray; set aside. In a large nonstick skillet, cook the beef, onion and peppers over medium heat until meat is no longer pink; drain. Add garlic, cook 1 minute longer. Stir in spaghetti sauce and seasonings; heat through. Spoon over spaghetti. Top with mushrooms and cheese. Bake, uncovered, at 350 for 25-30 minutes or until lightly browned. Let stand 5 minutes before serving.
