Preheat oven to 400 F.
Chop ½ of a yellow onion and 1 celery stalk. Core apples & dice; place all in a large container & toss w/ ½ tsp salt, ½ tsp sage, and ¼ tsp thyme.
Slice lengthwise into each pork chop to create a pocket in the meat.
Season pork chops w/ S&P, 1 tsp garlic powder, ½ tsp sage and ¼ tsp thyme on both sides and set aside.
Heat 1T olive oil in a large heavy oven-safe sauté pan over med-high heat. Add apple/onion mix & cook until soft, 5 to 7 mins.
Gently stuff the mix evenly into pork pockets until full. If you have metal skewers use them to close the pocket.
Wipe out pan and return it to heat w/ 1 T olive oil. Once hot, sear pork chops in the sauté pan for 2 to 3 minutes per side.
Place oven safe sauté pan in the oven & bake 15 to 20 minutes, or until the pork reaches an internal temperature of 145 F.
