Preheat oven to 350 degree F. Grease a 9x5-inch loaf pan.
In a large bowl combine the ground meat, bread crumbs, egg and 3/4 of the jar of Mom’s Meatloaf Starter. Mix well with your hands or a wooden spoon.
Place mixture in prepared loaf pan. Spread the remaining Mom’s Meatloaf Sauce over the top. Bake for 45-55 minutes or until a thermometer inserted into the center of the meatloaf has a temperature of 165 degree F. Allow meatloaf to rest 10 minutes. Cut into slices and serve.
