Place the slider/dinner rolls on a cutting board. Do not separate them. Slice the rolls in half and place the bottom half of rolls in a baking dish that has been sprayed for nonstick cooking spray.
Place the shredded chicken in a bowl and add the barbecue sauce. Stir to combine.
Put the BBQ shredded chicken on top of the rolls followed by bacon, sliced red onion and then cheese.
Place the top half of the slider/dinner rolls on top and brush with melted butter.
Bake in a 365 degree preheated oven until the tops of the rolls are golden brown and the cheese is melted.
