1 pound fresh Brussels sprouts, trimmed and cut in half
Vegetable cooking spray
Preheat oven to 425°. Stir together first 5 ingredients, 1 Tbsp. brown sugar, 1 tsp. rosemary, 1/2 tsp. salt, and 1/4 tsp. black pepper in a small bowl. Rub each pork chop with 1/2 tsp. olive oil; rub both sides of each pork chop with brown sugar mixture (about 2 tsp. on each chop).
Whisk together apple cider vinegar and remaining 2 Tbsp. brown sugar, 1 tsp. rosemary, 1/2 tsp. salt, and 1/4 tsp. black pepper in a small bowl; slowly whisk in remaining 3 Tbsp. olive oil until blended. Place apples, Brussels sprouts, and 1/4 cup vinegar mixture in a large bowl, and toss to coat.
Place pork chops in center of a lightly greased (with cooking spray) heavy-duty aluminum foil-lined sheet pan; place apple mixture around pork chops.
Bake at 425° for 12 minutes; turn pork chops over, and bake 10 to 14 minutes more or until a meat thermometer inserted in thickest portion registers 140°. Transfer pork chops to a serving platter, and cover with foil to keep warm. Stir apple mixture in sheet pan, and spread into an even layer.
Increase oven temperature to broil, and broil apple mixture 3 to 4 minutes or until browned and slightly charred. Transfer apple mixture to a medium bowl. Toss together apple mixture and remaining vinegar mixture. Season with kosher salt, and serve with pork chops.
