This is just the basic meatball recipe I use when making spaghetti, meatball sandwiches, Catalina Meatballs, etc. I bake them and use ground round so they are pretty low fat.
1 pound lean ground beef (93/7)
1/2 cups dry bread crumbs
1/4 cup skim milk
1 t onion powder
1 t garlic powder
1/2 t Worcestershire sauce
Mix ingredients; shape into twenty 1 1/2-inch balls (can make them larger or smaller - your preference). Bake in 13x9x2 inch pan on a rack so grease falls away while cooking, in 400 degree oven until light light brown, 20 to 25 minutes.
