Double Baked Potatoes
["6 medium size baking potatoes", "1 medium to large onion, diced", "1 (16 oz.) pkg. bacon, cooked and crumbled", "1 1/2 c. cooked, smoked ham, cut in small cubes", "1 1/2 c. cheese (I use part Mozzarella and part Cheddar)", "2 Tbsp. butter or margarine", "1/4 c. milk"]
["Wash the potatoes, rub them with oil and bake at 350\u00b0 until done.", "Let them cool and cut in half lengthwise, leaving about 1/4-inch around the shell.", "Scoop out the potato.", "Set the shells aside."]
