Mix coleslaw with dressing to taste and refrigerate for several hours to soften and combine flavors.
Cut thawed puff pastry into small squares, about 8 squares per 1/3 sheet.
Place in a silicone mini muffin pan or a sprayed or greased mini muffin pan.
Top each square with a heaping portion of cooked shredded pork or beef. Drizzle liberally with a thick BBQ sauce.
Bake at 400 for 15-20 minutes until pastry is done. Carefully remove from pan. Serve with slaw and crispy onions, or assemble cupcakes and arrange on a platter. Serve warm or at room temperature.
