Preheat the oven to 375℉ and line a rimmed baking sheet with tin foil.
Slice the buns in half and remove the top bun and set it aside. Place the bottom bun on the baking sheet and layer pulled pork on the bun. Top with a dollop of BBQ sauce and replace the top bun.
In a small microwaveable bowl, melt together the butter, Worcestershire sauce, onion salt and poppy seeds. Mircowave for 30-60 seconds, until melted. Stir the butter mixture and pour it over the top of the buns. Make sure there are poppy seeds on the top of each bun. Cover the buns and bake for 10 minutes. Remove the foil and bake for another 5 minutes. Remove from the oven.
If using the slaw, once the sliders have cooled for 5 minutes, remove the top bun and add some slaw. Replace the tops and serve!
