In a large mixing bowl combine beef, pork, eggs, bread crumbs, garlic and tomato relish. Finish with olive oil, and then pack into a 9-inch loaf pan and place in the middle of a preheated 350 degree oven. Bake for 35 to 40 minutes or until the center of the meat loaf reaches 170 degrees.
Finish the meat loaf with remaining tomato relish and broil at 500 degrees until tomato relish begins to crust. Allow meatloaf to cool before slicing.
Chop tomatoes, peppers, and onions into a medium dice. Saute over high heat. Finish with ketchup. Lower heat. Reduce to a simmer.
