In a baking dish, slice yeast rolls in half to separate top and bottom using a serrated knife and begin dressing the sliders
To dress the sliders, first brush 1-2 tbsp of bbq sauce, adding a layer of shredded chicken, and top with pickles and onion
Finish sliders by laying the top layer of rolls and brush melted butter over the rolls and place the baking dish into the oven for 10mins, until rolls are golden brown
Once rolls are browned and chicken is lightly heated, remove the baking dish from the oven and serve with your favorite bbq sandwich toppings
