Place spice rub ingredients in blender and pulse until coarsely ground.
Rub pork chops liberally on both sides with the rub. Store extras in an airtight container for later use.
Preheat grill to high and sear chops on both sides, 2-3 mins per side. Meanwhile, mix glaze in saucepan on medium heat. Adjust seasonings to your taste.
Turn grill to med-low and continue cooking until internal temp is 150°F (depending on thickness of chops). Baste with glaze during last 2 minutes of cooking. Let rest 5 minutes before serving.
