If you're trying to cut down on carbs, spaghetti squash makes an excellent pasta replacement. Because it's a vegetable, the texture is a little different, but it has a good mild flavor and the sauce is still the star. Seasoned ground beef and tomato sauce make this spaghetti squash dish a complete meal. The spaghetti squash is separated into strands and then baked with a beefy tomato sauce and cheddar cheese. Use ground turkey or italian sausage in place of the beef, if desired. See the tips and variations below the recipe. If you aren't counting carbs, serve this dish with crusty bread and a tossed salad.
