Mix all ingredients together in large bowl by using your hands. (Yes, it's easiest to just get messy and mix away!) If your mixture is a little too dry add a little more steak sauce or Worcestershire sauce. If your mixture is a little too moist, add a little more bread crumbs.
Shape into 1 inch balls. Place on foil lined baking sheets with a shallow rim to prevent drips and bake at 350°F for about 20-30 minutes, turning occasionally with tongs.
Allow to cool. Divide into 5 portions in labeled, freezer safe containers.
