Ingredient Additions and Recommendations:

Ricotta cheese – add 4-6 dollops of ricotta cheese with the pasta and meatballs before baking. It will give it a delicious lasagna flavor and consistency.
Spices – most pasta sauces will already be well spiced, however, you can add extra garlic powder, basil, oregano or Italian seasoning to your liking.
Shredded or grated Parmesan cheese for topping – this dish pairs wonderfully with fresh grated Parmesan cheese just before serving.
