Place pork tenderloin into a resealable plastic bag.
Combine all marinade ingredients, except honey into a small bowl. Warm honey in the microwave for about 8-10 seconds (or until it becomes more liquified), and add to the marinade mixture. Stir to combine.
Add marinade mixture to pork making sure that all surfaces and coated well. Release excess air from the plastic bag, and seal shut. Place into the refrigerator for 2-4 hours.
Preheat grill for medium heat. This is a setting of 325 degrees F on a pellet grill.
Remove pork from bag and place onto the grill grate. Gently pour some of the remaining marinade on top of the tenderloin. Close lid and cook for 10 minutes. Turn and cook for another 10 minutes, or until the internal temperature at the thick part of the pork reaches at least 140 degrees F.
Once cooked, remove from heat and place onto a clean cutting board. Tent with aluminum foil and let rest for 5 minutes. Slice into 1/2 inch thick rounds and serve.
