Cheese & Sausage Stuffed Shells

Directions

• Preheat oven to 350°. Cook pasta shells according to package directions for al dente; drain and rinse with cold water. Meanwhile, in a large skillet, cook sausage and onion over medium heat 6-8 minutes or until sausage is no longer pink, breaking up sausage into crumbles; drain and return to pan. Add cream cheese; cook and stir until melted.
• Transfer to a large bowl; cool slightly. Stir in spinach and egg. Add 1 cup mozzarella, cheddar cheese, cottage cheese, Parmesan cheese, salt and pepper; mix well. In a small bowl, combine sauce ingredients. Spread 1-1/3 cups sauce onto bottom of a greased 13x9-in. baking dish and 2/3 cup sauce over the bottom of a greased 8-in. square baking dish. Fill pasta shells with sausage mixture; arrange over sauce. Top with remaining sauce.
• Bake, covered, 45 minutes or until pasta is tender. Sprinkle with remaining mozzarella cheese. Bake, uncovered, 5-10 minutes longer or until cheese is melted.
