Slice hawaiian rolls lengthwise then open so the insides are faceup on a baking sheet.
Place cheese on the top half then place rolls under the broiler in the oven for just a minute or two until cheese is melted and the other side is toasted.
In a bowl combine chicken, bacon, lettuce, tomatoes & ranch and mix well.
Pour mixture onto the toasted side of the rolls and top with crispy onions.
Place the cheesy layer of the rolls on top and slice into sliders.
