Marinate pork chops in Italian dressing and garlic for about 3 hours. Preheat the oven to 375 degrees. Individually wrap each pork chop in foil. Before sealing up the foil, pour barbecue sauce over the chop inside. Cook the chops for about 20 minutes, or until no pink is showing through. Peel three apples, chop into pieces and place in oven safe dish. Cover them with cinnamon, sugar and butter. Cook them for about 10 minutes at 375, just until soft. Get out two plates and place apples on each, and then place a pork chop on top of the apples. Add a bit more barbecue sauce
