Beefy Baked Ravioli

Preheat the oven to 450 degrees F (230 degrees C).

Crumble the ground beef into a large skillet over medium-high heat. Cook and stir until no longer pink. Drain grease, then stir in the spaghetti sauce and tomatoes.

Spread 1/3 of the sauce in the bottom of an 11x7 inch baking dish. Arrange 1/2 of the ravioli over the sauce. Sprinkle 1/2 of the mozzarella cheese and 1/2 of the Monterey Jack cheese over the ravioli. Repeat layers, ending with the last of the sauce on top. Cover with aluminum foil.
