|1||26-ounce jar spaghetti sauce|
|1||14.5-ounce can diced tomatoes, undrained|
|2||1-pound packages frozen ravioli, either beef or cheese or one of each|
|2||cups shredded Italian three-cheese blend or other Italian cheese|
|2||tablespoons Parmesan cheese|
Mix spaghetti sauce, tomatoes, and water (the water can be poured into the empty spaghetti sauce jar to shake and rinse it). Spoon 1 cup sauce mixture into the bottom of a 9x13-inch baking dish. Layer half the ravioli and 1 cup shredded cheese over sauce mixture. Top with remaining ravioli and sauce mixture. Sprinkle with remaining shredded cheese and cover with foil. Bake at 400 degrees F for 30 minutes. Uncover and bake an additional 15 minutes or until ravioli is tender. Sprinkle with Parmesan. Let stand 10 minutes.
