In a large mixing bowl stir the bread, egg and milk to completely combine and let it sit for 15 minutes. Mash up the mixture with a fork to make a smooth paste. Add all of the seasonings and cheese and mix well. Add the beef (or beef and pork mixture) and stir together until completely combined. Form the mixture into balls (about the size of a golf ball) and place on a GREASED baking sheet (for easier handling when forming meatballs, lightly wet hands with water and the mixture won't stick to your hands).

Bake in a preheated 400-degree oven for 20 minutes, turning over after 10 minutes. Drain the meatballs on a paper towel and place in a large glass bowl. Add 2 cups of your favorite spaghetti sauce and stir just enough to cover meatballs. Cover bowl with paper towel and microwave on medium for five minutes, stir, recover and microwave on low for an additional 20 minutes.
