First, whisk the broth and oil together in a small bowl. Add the soy sauce and whisk well. Whisk in the garlic powder, ginger and the salt. Stir in the peach preserves and mix well.
Next, pour the marinade onto pork chops and let marinate, refrigerated for 30 minutes or place in a resealable plastic bag and marinate in the refrigerator overnight.
Then, preheat an outdoor grill. Add the marinated pork chops to the grill and discard the marinade. Cook until pork is no longer pink, about 15 minutes depending on the thickness of your chops.
Finally, serve topped with additional peach preserves and enjoy!
