This recipe is a frugal cook's dream because it's inexpensive to make, easily doubled and freezes well. Try it with the Italian-flavor turkey sausage (I promise you can't tell it's turkey)- you'll love the flavor of this super-lean source of protein!
My favorite tip for this recipe: Make one batch for now, one for later. Pasta can be frozen baked or unbaked. Thaw in refrigerator overnight, reheat or bake as needed. If casserole was frozen unbaked, add 10-15 minutes additional cooking time.
