Combine chopped pork, ¾ cup jerk sauce, olive oil and some salt in a large zip-top bag. Let it marinate in the refrigerator for at least 4 hours or overnight.
Thread the chopped pork onto skewers and let them sit at room temperature for 20 minutes.
Preheat outdoor grill to high heat (400ºF). Grill the skewers for 4-5 minutes per side or until browned and cooked through to an internal temperature of 145˚F with a 3 minute resting time. (A wireless thermometer works great!)
