If you’d like to make a lighter version of this recipe, you can substitute the traditional pasta for spaghetti squash. It’s a great way to cut the carbs without subtracting the flavor. Just slice your spaghetti squash and lay flat on a roasting pan. Add some olive oil and bake at 400º for 30 minutes until softened. Use a fork to shred the spaghetti squash.

Of course, it’s a bit more time consuming than the original pasta version. Both are equally delicious! Save your leftovers in an air-tight container. You can either microwave or bake in the oven again to re-heat.
