Preheat grill or smoker to 350 F.

Season the tenderloin with a good sprinkle of salt and black pepper.

In a bowl, whisk together molasses, Worcestershire sauce and soy sauce.

Brush over pork tenderloin, save any extra sauce for brushing on during cooking.

Place on grill and cook for roughly 25-30 minutes (depending how thick your tenderloin is) or until a meat thermometer reads 150 F..

During the cooking you can brush on more of the sauce if desired.

Let meat rest for 10 minutes then slice and serve.
