Trim any excess fat from the pork chops and season with salt and pepper on both sides.
Heat oil in a large skillet over medium heat. Once hot, add the pork chops and sear for 2 to 3 minutes per side, or until the chops are golden brown. Transfer the chops to a plate (it's ok if they are slightly undercooked, they will finish cooking when put back in the pan).
Using the same pan, melt butter. Add the sliced apples, chickpeas, and onions. Sauté until everything is caramelized and the apples are golden brown with some charred spots, about 8 minutes.
Whisk together the chicken stock and mustard in a small bowl. Add the stock mixture to the pan, and stir. Place the chops back in, sprinkle everything with rosemary, sage, and thyme. simmer for 2 to 3 minutes on medium-high, or until the sauce is reduced by half and the pork chops have reached an internal temperature of 145°F. Enjoy!
