1-3/4 cups sliced fresh mushrooms 
1 medium onion, chopped 
1 medium green pepper, chopped 
2 cans (14-1/2 ounces each) Italian diced tomatoes

DIRECTIONS
Cook pasta according to package directions. Meanwhile, in a Dutch oven, cook the beef, sausage, mushrooms, onion and green pepper over medium heat until meat is no longer pink; drain.
Drain pasta; add to the meat mixture. Stir in the tomatoes, sausage and garlic spaghetti sauce, salsa and pepperoni.
Divide half of pasta mixture between two greased 13-in. x 9-in. baking dishes. Sprinkle each with 1/4 cup Swiss cheese, 1 cup mozzarella cheese and 1/3 cup Parmesan cheese. Spread 3/4 cup of three-cheese spaghetti sauce over each. Top with remaining pasta mixture and three-cheese spaghetti sauce. Sprinkle with remaining cheeses.
Cover and freeze one casserole for up to 3 months. Cover and bake remaining casserole at 350° for 25 minutes. Uncover; bake 10 minutes longer or until cheese is melted. 
To use frozen casserole: Thaw in the refrigerator overnight. Remove from the refrigerator 30 minutes before baking. Cover and bake at 350° for 45 minutes. Uncover; bake 10 minutes longer or until cheese is melted. Yield: 2 casseroles (6 servings each).
