In a blender, add all the ingredients except pork chops and process until well combined. In a Ziploc, place pork chops and pour marinade over. Close bag and massage/flip it until well coated. Transfer to the fridge for 8 to 10 hours.
Preheat BBQ to 550ºF. Transfer chops on a plate and discard marinade. Place pork chops on the grill and cook 5-6 minutes per side or until internal temperature reaches 135-140ºF. 4 minutes before the end of cooking, place pineapple slices and grill 3 minutes per side. Serve with vegetable medley.
