Cook ground meat in large heavy pot over medium high heat. Stir and break up pieces until cooked through. Drain any excess grease. Turn heat off.
Add pasta sauce and diced tomatoes with juices to the pot. Add oregano, black pepper, garlic powder, onion powder, and sugar. Stir to incorporate well.
Spread 1/3 of the meat sauce evenly onto the bottom of a 9x11 baking dish. Arrange 1/2 of the frozen ravioli over the sauce. Spread 1/2 of mozzarella and 1/2 of Colby cheeses over the ravioli.Repeat layers. You should end with last 1/3 of the sauce on top. Sprinkle top evenly with Parmesan.
If using right away: cover loosely with aluminum foil and bake at 450F for 30 minutes, or until ravioli is tender.If not using right away: cover tightly with foil and place in fridge. When ready to use, loosen foil and bake at 450F for 50-60 minutes.
