Using a serrated knife cut through the middle of the potato rolls. Place the bottoms side by side on the pan. Set the tops aside.

Brush the bottoms of the rolls with about 1/3 of the seasoned butter.
Layer 1/2 of the cheese slices on the bottom of the rolls then arrange the chicken and bacon over the cheese. Tear cheese slices if needed, to fit.
