Grilled Pork Tenderloin with Mustard Fruit

Although tenderloin is my least favorite cut in most animals I give it a bit of a free pass with pork due to pork's naturally fatty make up. But even with pork it tenderloin is definitely on the low end of the flavor spectrum. To wake it up a little I season it pretty liberally before grilling than finish it with some zippy mustard fruit which I always have stashed in my fridge.
