1. Place pork chops, soy sauce, vinegar and oil in a large ziplock bag; seal. Turn bag several times to coat chops with marinade; refrigerate for 15 minutes.

2. Remove pork chops from bag; discard excess marinade. Warm a grill or grill pan to medium-high heat. Grill pork chops until cooked through, turning once, about 3 1/2 minutes per side. Transfer pork chops to a platter, sprinkle with cilantro and scallions, and serve.
