Place pork chops on a cutting board and, using a very sharp knife with the blade turned parallel to the board, cut a pocket into the fat side of the chop. Cut almost all the way to the bone, and be careful to leave about ¼-inch uncut on the two sides. Place pork in the brine for 1 hour. (see brine recipe at end)
Place all remaining ingredients except the additional olive oil and lemon wedges in the bowl of a food processor or spice grinder, and process until finely ground and all herbs are well mixed together.
Remove the pork from the brine and pat dry with paper towels inside and out. Divide the stuffing and gently spread into the pockets. Seal them by using trussing skewers or bamboo skewers.
Set a gas grill at hottest setting. If using charcoal, keep the hot coals to one side. Rub the exterior of the chops with some olive oil and then season with salt and pepper (as the brine is salty, be cautious not to over-salt them at this stage). When grill is ready, place chops directly over heat to sear and immediately reduce heat to medium. (For charcoal move to indirect heat.) Grill 4 minutes per side, depending on the thickness of the chops, or until done. Serve drizzled with olive oil with lemon wedges.
