Three-Cheese Jumbo Shells Recipe

In a large skillet, cook beef and onion over medium heat until the meat is no longer pink; drain. Stir in the water, tomato paste, bouillon and oregano. Cover and simmer for 30 minutes. Meanwhile, in a large bowl, combine the ricotta cheese, 1 cup mozzarella, Parmesan cheese and egg. Stuff shells with the cheese mixture. Arrange shells in a greased shallow 3-qt. baking dish. Spoon meat sauce over shells. Cover and bake at 350° for 30 minutes. Uncover; sprinkle with remaining mozzarella cheese. Bake 3-5 minutes longer or until cheese is melted. Yield: 6-8 servings. If there is no "Sell By" date on a ricotta cheese carton, it should be stored in the refrigerator no longer than 5 days after purchase. Ricotta and other soft cheeses should be discarded as soon as any mold appears.
