PREPARATION:
- Combine all ingredients, except pork, in medium bowl; mix well.
- Pierce pork a few times with fork. Place in large resealable food storage bag. Pour orange juice mixture into bag. Close bag securely, turning to coat. Marinate in refrigerator overnight, turning occasionally.
- Prepare grill for direct cooking. Drain pork; reserve marinade.
- Place pork on grid. Grill, covered, over medium-high heat 45 to 60 minutes or until internal temperature reaches 155°F when tested with meat thermometer inserted into thickest part of pork, turning occasionally. Transfer roast to cutting board; cover with foil. Let stand 10 to 15 minutes. Internal temperature will continue to rise 5°F to 10°F during stand time.
- Meanwhile, pour reserved marinade into large saucepan. Bring to a boil over high heat. Cover, reduce to a simmer and cook 20 minutes or until onions are soft.
- Slice or "hack" pork into bite-size pieces. Add pork to saucepan with cooking marinade. Bring to a simmer. Simmer, uncovered, 15 minutes.
