DO-AHEAD TIP: Marinate pork overnight or for at least 4 hours (see recipe).
Place pork tenderloin in a large zipper-topped plastic bag. In a medium bowl, whisk together remaining ingredients.
Pour mixture over tenderloin, seal bag and refrigerate overnight or for at least 4 hours. At the time of cooking, preheat an outdoor grill to MEDIUM-HIGH.
Remove pork from marinade and wrap in foil. Place on grill, cover and cook for 20 minutes.
Uncover, remove foil and grill for 5 to 10 minutes per side or until cooked through.
