Add the olive oil to the skillet, when the oil shimmers, add the pork and sear on both sides for 2-3 minutes. Reduce the heat to medium and continue cooking for about 5 minutes, or until the pork chops are cooked through. Remove the pork from the pan to a plate. Spread each pork chop with a layer of apple butter. To the skillet, add the butter, garlic, apples, and sage. Cook 1-2 minutes then remove from the heat. Slide the pork back into the the skillet. Drizzle the balsamic vinegar over the pork. Transfer the skillet to the oven and broil for 2-3 minutes or until the apples are lightly charred. Remove from the oven and top with fresh thyme. Spoon the butter over the pork chops. Serve and enjoy!
