I got this recipe from my sister, Melanie. It is one of Josh's favorites, and mine too.
1 jar (28 oz.) Spaghetti Sauce
1 package (25. oz.) frozen Cheese Ravioli, cooked & drained
2 cups Cottage Cheese
4 cups Mozzarella Cheese
1/4 cup grated Parmesean Cheese
Spread 1/2 cup sauce in an ungreased 9x13 dish. Layer with half of the ravioli, 1 1/4 cup of sauce, 1 cup Cottage Cheese and 2 cups Mozzarella Cheese. Repeat layers. Sprinkle with Parmesean. Bake at 350 for 30 minutes or until hot and bubbly.
