Season pork chops with salt and pepper to taste, and arrange in a medium oven safe skillet. Top pork chops with onions, sweet potatoes, and apples. Sprinkle with brown sugar. Season with 2 teaspoons pepper and 1 teaspoon salt.
Cover, and bake 1 hour in the preheated oven, until sweet potatoes are tender and pork chops have reached an internal temperature of 145 degrees F (63 degrees C).
