1 jar (26 to 28 ounces) tomato pasta sauce (any variety)
1 package (25 to 27 1/2 ounces) frozen cheese-filled ravioli
2 cups shredded mozzarella cheese (8 ounces)
2 tablespoons grated Parmesan cheese
Heat oven to 350°F. Spray bottom and sides of rectangular baking dish 13x9x2-inches, with cooking spray. Spread 3/4 cup of the pasta sauce in baking dish. Arrange half of the frozen ravioli in single layer over sauce; top with half of the remaining pasta sauce and 1 cup of the mozzarella cheese. Repeat layers once, starting with ravioli. Sprinkle with Parmesan cheese. Cover with aluminum foil and bake 40 minutes. Remove foil; bake uncovered 15 to 20 minutes longer or until bubbly and hot in center. Let stand 10 minutes before cutting.
