Portobello Mushroom Stroganoff but there’s no reason why you couldn’t throw in some browned ground beef too.
Another thing that’s really good is a cross between lasagna and spaghetti pie. Put some marinara sauce in the bottom of a casserole dish, layer some of the noodles, some ricotta cheese, maybe some sauteed mushrooms if you like, your sauteed ground beef, more noodles, more sauce, more ricotta, more noodles, then some grated mozzarella on top. Bake at 425 for 15 to 20 minutes.
