This is a recipe I was given from a lady from Italy. She told me that the secret of mouth watering meatballs is not to cook them before adding them to the sauce, as cooking them in the sauce will not only add more flavor to the sauce, but also to the meatballs. What I do is make these a day ahead of time, with my sauce. Then, I refrigerate it over-night, which makes any fat rise to the top and harden, where it is easily removed. This process also allows all of the flavors to "marry" together, making it especially delicious!
