Cook raviolis through to the directions on the package. While they are cooking, heat oven to 350 degrees.

Mix the meat sauce with the ricotta so it is combined.

Spray an oven safe dish with cooking spray. Put about a half cup of the sauce on the bottom of the dish and spread it out. Layer on a single layer of ravioli. Top with some mozzarella cheese, a sprinkle of parmesan cheese and another 1/2 cup of sauce.

Keep doing this until you have layered all the raviolis. Try to only use a half of the mozzarella cheese while layering, On the very top there should be the layer with the remaining sauce, top that with all of the mozzarella that is left.

Cook this for about 25 minutes or until bubbly, no need to top it with foil. Let it cool before serving, this baby is hot!
