Spaghetti and meatballs Lidia Bastianich

Everybody loves meatballs. I feel like meatballs are part of Americana. They belong on the American table and this is a great and simple recipe. It calls for three types of meat but a combination of any two or even one will work as well. It freezes well, but is best frozen in smaller quantities, (1/2 pint, 6-8 meatballs and sauce) so that it reconstitutes quickly.
