In a zip top plastic bag, combine first 6 ingredients, add pork, and marinate in refrigerator for 1-2 hours. Remove tenderloins and discard marinade.
Heat gas or charcoal grill to 350-400 degrees, place soaked plank on grill grates, close lid, and allow to heat for 3 minutes. Open lid, flip plank, and continue to heat for 3 more minutes until a light smoke develops. Place tenderloins directly onto plank and close lid. Depending on grill temperature, indirect heat may be necessary. Grill for approx. 15-20 minutes or until meat thermometer reaches 145 degrees.
We recommend serving pork just slightly pink (medium).
Great served with peach or mango salsa
