Pork chops are great when marinated in Italian dressing. Marinate the pork chops in this for about an hour, longer for more flavor. Sprinkle with salt and pepper. Allow your grill to get very hot. If you are using an indoor portable grill, turn it to the maximum temperature and allow it to heat up. Grill the pork chops to the desired doneness, usually about 6 minutes per side. Make sure that you flip the meat without puncturing it to allow the juices to escape.
