In a 12-inch cast-iron skillet, cook bacon over medium-high heat until crisp. Remove bacon using a slotted spoon, and let drain on paper towels, reserving drippings in skillet.
Sprinkle pork chops with 1 teaspoon salt and ½ teaspoon pepper. Add pork chops to skillet; cook until browned, about 2 minutes per side. Remove from skillet.
Add cabbage, apple, and onion to skillet; cook, stirring frequently, until crisp-tender, about 4 minutes. Add ½ cup water, mustard, remaining ½ teaspoon salt, and remaining ¼ teaspoon pepper, stirring to combine. Top with pork chops. Cover and cook over medium-low heat until tender, 15 to 20 minutes. Sprinkle with bacon. Serve immediately.
