Whisk together the pomegranate juice, garlic, honey, tarragon, large pinch of salt and ground pepper to make the marinade. Now, if you don't have tarragon you can use any herb (thyme or basil would be good) you like but the tarragon went really well with the pomegranate juice.
4 oz pomegranate juice, 3 cloves minced garlic, 1 tablespoon honey, 1 teaspoon dried tarragon, kosher salt and ground pepper.
Layer the pork chops and onion slices vertically in a quart sized baggie. Pour the marinade over and seal removing as much air as possible. Refrigerate for at least an hour.
Heat an outdoor grill. Cook the chops and Vidalia slices 3-4 minutes a side. Longer if you have thick chops. My onion actually took longer then the pork!
