Pork Tenderloin on the Grill

Last night I managed to pull off some pretty solid late fall grilling for my kids; I grilled this pork tenderloin and roasted some potatoes.  My kids wanted some grilled apple slices as well, which are shown here in the picture alongside my sweet 10" (26cm) Wusthof chef's knife, would could almost double as a sword:

The sauce is my simple honey mustard, but I improved it with a kick of soy sauce this time around.

Very satisfying!
