In a large bowl, mix potatoes, oranges, orange peel, red onions, oregano, salt and pepper. In a small bowl, whisk mustard, vinegar and garlic, then add olive oil in a thin stream, whisking until emulsified. Pour dressing over potato and orange mixture, and toss gently to combine.
Tear off 6 12-inch sheets of heavy-duty aluminum foil and stack in two piles (three sheets each). Pour half the potato mixture into center of each top sheet of foil. Shape ingredients on each sheet into a pile 6 inches by 6 inches, and pour any dressing left in the bowl over the piles. Wrap ingredients in each pile in the top sheet of aluminum foil, sealing it tightly, followed by the second and third sheets.
Prepare a fire in the grill. When flames have subsided and coals are glowing, carefully remove grill grate, and set hobo packs directly on coals. With tongs, gather a few hot coals around hobo packs. Replace grill grate, and let cook 25 minutes. Remove grill grate, and with kitchen mitt or spatula, remove hobo packs from grill. Cut a vent through top of each pack, and serve.
