With this spaghetti squash and meatballs recipe, you can reduce the carbohydrates and increase the vegetable servings by skipping pasta and serving the Italian-seasoned turkey meatballs and quick, homemade marinara sauce over thin strands of cooked spaghetti squash instead. Cooking the squash first in the microwave and then in a skillet to cook off the extra moisture, gives the squash a more spaghetti-like texture.
