FRY METHOD: Fry meatballs in a large skillet, between medium-low and medium heat in 1-2 tablespoons olive oil (or fry between 275 F - 300 F in an electric wok or electric skillet), alternately turning and covering until browned/steamed and meat is just cooked until done, yet moist.
STEAM METHOD: Heat a large saucepan filled halfway with marinara sauce over medium heat. Add raw meatballs, then 1/2 cup water. Cook until slightly browned on bottom, then turn meatballs using a slotted spoon. Add a little more water and continue cooking until done. Re-season sauce if necessary just to keep meatballs in before adding to spaghetti, or a meatball sandwich. Top with chopped parsley, a little olive oil, fresh ground pepper and a sprinkle of freshly grated parmigiano reggiano cheese.
