Cut pork chops into cubes about 1 1/2" - 2" square and place in zip loc bag. Combine marinade ingredients and pour over meat. Marinate in refrigerator for 6-24 hours.
Preheat grill to high and let meat come to room temperature. Thread on to skewers, pressing meat closely together so it doesn't spin on the grill. (Double skewers are great if you can find them.)
When grill is hot, place Souvlaki skewers on grill and reduce heat to medium-high. Grill until very well browned on all sides, about 20-25 minutes. This is good served with Tzatziki sauce, a traditional Greek sauce made from yogurt, cucumbers, onions, garlic, and dill.
