Prep your ravioli according to the package directions and drain.
Brown your beef, once the beef is browned and you have drained off any grease that you would like removed, add in the mushrooms.
Remove from heat and add in your pasta sauce. In a large baking dish layer half the meat sauce, then spread the ravioli out on top of the sauce, cover with 1 c of the cheese, add the rest of the sauce and then top with the remaining cheese.
Bake in a preheated 350° oven for 20 minutes or until bubbly and cheese is melted.
