How to Make It
Season pork chops with 1 teaspoon salt and 1/2 teaspoon pepper. Heat oil in a large cast-iron skillet over medium-high. Add pork chops to skillet; cook, turning occasionally, until browned and an instant-read thermometer inserted in thickest part of chop registers 135°F, 5 to 6 minutes per side. Set aside.
Cut each apple lengthwise into quarters, and discard cores. Thinly slice apple quarters lengthwise; stack slices, and cut lengthwise again into thin sticks.
Whisk together mayonnaise, vinegar, poppy seeds, and hot sauce in a large bowl; season with remaining 1/2 teaspoon salt and remaining 1/4 teaspoon pepper. Add apple sticks, celery, celery leaves, parsley, and chives; toss to combine. Serve immediately with pork chops.
