In a small bowl, mix together the balsamic vinegar, Dijon mustard, olive oil, and minced garlic to make the marinade.
Season the pork chops with salt and pepper, then place them in a shallow dish. Pour the marinade over the chops, ensuring they are well-coated. Let them marinate for at least 10 minutes.
Preheat a skillet over medium-high heat. Sear the pork chops for about 5 minutes on each side, until they are browned and cooked through.
Once cooked, let the pork chops rest for a few minutes before serving. Serve hot, drizzled with any remaining balsamic marinade from the pan.
Notes
For best results, use a high-quality balsamic vinegar.
