Make pesto (or you can substitute pre-made pesto found at grocery store).
Lightly spray a baking dish and place the bottom half of slider rolls in dish.
Spoon pesto over the bottom half of rolls.
Layer chicken and then cheese on top of pesto.
Place the tops of the rolls back on sliders and brush tops with melted butter.
Cover tightly with aluminum foil and bake for 15-20 minutes. Sliders will be ready to eat when cheese has melted.
Serve and enjoy!
