Grill the pork according to the package instructions. Keep the grill moderately heated, and turn the tenderloin often to avoid burning.
While the pork is grilling, set out the fixings for the sliders. I like to set mine up fix-it-yourself style, so each person can make their slider how they'd like (in case there's a picky one in the bunch!)
If you'd like to toast the buns, lightly butter them and place them butter-side-down on the grill until lightly toasted.
When the pork is done (145 degrees), remove it from the grill and let it rest on a cutting board for a few minutes. Slice the pork thinly and let people assemble their own sliders.
