It's so hard to cook for a family when we all have different likes and dislikes. Spaghetti is one of those meals that is so easy to customize.
If you are trying to cut the carbs, sauté a couple of zucchini in a skillet with a little drizzled olive oil. Add some garlic and dried oregano, salt and pepper to taste. You can also skip the olive oil and sauté the zucchini in chicken broth to cut fat. Put your meat sauce and parmesan cheese on top. This is so much more flavorable than pasta, I don't miss it at all.
