Meatballs make awesome and convenient leftovers, so it's always a good idea to cook them in big batches. Plus, they're extremely versatile, and you can pretty much prepare them however you like. Simpy mix your preferred ingredients into the ground beef, roll into balls, and bake them up until golden brown. Eat them with pasta or rice in your favorite sauce. Or toss them onto a sub roll with grated cheese and place under the broiler until melted for a satisfying meatball sammy.
