Mix honey, Korean pepper paste, soy sauce, sesame oil, garlic powder and ginger in small bowl until well blended. Reserve 2 tablespoons marinade for brushing. Place pork in large resealable bag. Add remaining marinade; turn to coat well. Massage pork and marinade for 4 to 5 minutes.
Refrigerate 30 minutes. Remove pork from marinade. Thread 1 piece of pork onto each skewer. Discard any remaining marinade.
Grill skewers over medium-high heat 2 minutes per side or until pork is cooked through, brushing with reserved marinade. Sprinkle skewers with green onions and sesame seed.
