In a large skillet heat the oil until shimmering. Season the pork chops with salt and pepper. Brown the chops, turning once. Remove from the skillet to a plate.
Saute the onion and garlic in the remaining drippings until the onion goes clear.
Add the barbecue sauce, liquid, salt, and pepper.
Return the chops and any juices to the pan and cover and simmer until the chops are tender, turning once. This may be 10 minutes for thin chops, or up to 20 or 30 minutes for thicker pork chops. Serve immediately.
