Prepare campfire or grill for medium heat. In a large bowl, toss potatoes with sausage, bacon, onion, parsley, salts and pepper.
Divide mixture among eight 18×12-in. pieces of heavy-duty nonstick foil, placing food on dull side of foil. Fold foil around potato mixture, sealing tightly.
Place packets over campfire or grill; cook 15 minutes on each side or until potatoes are tender. Open packets carefully to allow steam to escape. If desired, sprinkle with additional parsley.
