Make the marinade by combining the garlic, olive oil, hoisin sauce, soy sauce, rice vinegar, ginger, and sriracha sauce in a zip-lock bag and mixing them thoroughly.
Add the pork chops and marinate in the refrigerator for at least 2 hours.
Remove the pork chops from the refrigerator 30 minutes before you start grilling.
Grill the pork chops by heating the grill pan over medium-high heat until hot. Coat the pan with olive oil cooking spray, then add the pork chops.
Cook for 5-6 minutes, then flip the pork and grill for 5-6 minutes, or until the pork is cooked through.
Let the meat rest for 5 minutes before slicing and serving. Enjoy.
