Place chops in a single layer in a 9x13 glass dish or in a gallon resealable plastic bag. Add balsamic and EVOO and massage to thoroughly distribute over the pork chops. Allow the meat to marinate at least 2 hours in the refrigerator. If marinating in a 9x13 glass dish, flip them halfway through.
Once marinated, warm grill. Remove pork chops from marinade and place on a plate or cutting board. Season each side of the pork chops with Back of the Yards Garlic Pepper Butcher's Rub.
Grill chops until internal temperature reaches 145 degrees F, about 4 minutes each side.
