Spinach Stuffed Shells

Steam, chop and cool the spinach. About 1 1/2 hours before you want to serve, boil and drain shells. In bowl combine cooled spinach, ricotta cheese, mozzarella cheese, salt and pepper. Stuff each shell with this mixture and arrange in a baking dish. If very large shells are unavailable, stir shells into mixture and pour into baking dish.

In frying pan, brown ground beef and pour off fat. Add spaghetti sauce, mushrooms and Italian seasoning. Simmer 10 minutes. Pour meat sauce over shells. Bake at 350 degrees for 25 minutes. Sprinkle with Parmesan cheese and bake 5 minutes longer.
