Cut three 20 x 3 inch strips of heavy-duty aluminum foil. Crisscross the strips so they resemble te spokes of a wheel. Place meat loaf in the center; pull the strips up and bend the edges to form handles. Grasp the fooil handles to transfer loaf to a 3-qt slow cooker. (Leave the foil in during cooking time)
