When I make spaghetti sauce I like to freeze the leftovers to use later to make this recipe. You need 5 cups of spaghetti sauce with meat = 24 ounce jar marinara and 1 lb ground beef. Pour water in pan, then add noodles, add spaghetti sauce on top, cover and let cook for 15 minutes. Continue with the recipe as written above.
