Grilled Teriyaki Pork Tenderloin

Directions

1. In a small bowl, combine mustard and teriyaki marinade; pour 1 cup into a large resealable plastic bag. Add pork and garlic; seal bag and turn to coat. Refrigerate 6 hours or overnight. Cover and refrigerate remaining marinade.
2. Prepare grill for indirect heat using a drip pan. Moisten a paper towel with cooking oil; using long-handled tongs, rub on grill rack to coat lightly. Drain and discard marinade from pork.
3. Place pork over drip pan and grill, covered, over indirect medium-hot heat for 25-40 minutes or until meat reaches desired doneness (for medium-rare, a thermometer should read 145°; medium, 160°), basting with reserved marinade and turning occasionally. Let stand 5 minutes before slicing. Sprinkle with onion.
