Preheat the oven to 500℉. Line a baking sheet with parchment paper or lightly spray with nonstick cooking spray.
Finely chop the coleslaw if it's not in bite-size pieces.
Slice potatoes into ⅛" slices with a mandoline slicer. Lay them in a single layer on the baking sheet.
Melt butter in a small dish and add garlic salt. Brush the tops of potato slices with garlic-salted butter.
Bake potato slices in the oven for 15-20 minutes, rotating the potatoes halfway for even cooking.
While it bakes, heat the leftover BBQ pulled pork just a few minutes before the oven is finished.
Once done, remove from the oven and top each potato chip with BBQ pulled pork and coleslaw.
Notes
Even if you don't have leftover pulled pork on hand you can easily find BBQ pulled pork in the refrigerator section of the grocery store. Curly's and Jack Daniel's both make a great BBQ pulled pork that's microwavable.I like to get a bag of Dole classic coleslaw and add T. Marzetti's slaw dressing to it for a quick coleslaw.
