Place pork tenderloins in resealable plastic bag; set aside. In small bowl, combine first 8 marinade ingredients; pour over pork. Seal bag; refrigerate for at least 1 hour to marinate, or up to 24 hours to enhance flavor. Preheat grill to medium-hot. When ready to grill, remove pork from marinade and place on grill. Cook covered for about 10 minutes per side or until the internal temperature of pork is 160º. Meanwhile, place the pineapple chunks on the skewers; place on grill during the last 6 minutes of grilling time, turning after 3 minutes. To serve, slice pork into 1/2-inch slices and serve with grilled pineapple.
