Ingredients
8 cups uncooked pasta (four different shapes)
2 pounds ground beef
2 medium green peppers, chopped
2 medium onions, chopped
2 cups sliced fresh mushrooms
4 jars (26 ounces each) meatless spaghetti sauce
2 eggs, lightly beaten
4 cups (16 ounces) shredded mozzarella cheese

Directions
Cook pasta according to package directions. Meanwhile, in a large skillet, cook the beef, green peppers, onions and mushrooms over medium heat until meat is no longer pink; drain.

Drain pasta and place in a large bowl; stir in the beef mixture, two jars of spaghetti sauce and eggs. Transfer to two greased 13-in. x 9-in. x 2-in. baking dishes. Top with remaining sauce; sprinkle with cheese. Bake, uncovered, at 350° for 25-30 minutes or until heated through. Yield: 2 casseroles (8-10 servings each).
