Melt the butter. Add the Buffalo sauce and ranch dressing and combine.

Cut the Hawaiian rolls in half horizontally to make a top and a bottom.

Place 2 long sheets of aluminum foil on a baking sheet. You will need enough foil to completely wrap the sliders for baking. Place the rolls' bottom half in the middle of the foil. Add a layer of pepper jack cheese to cover the bottom layer of bread.

Pour the sauce over the chicken into a medium-sized bowl. Stir to mix. Add the chicken to the cheese layer, spreading it out evenly.

Place another layer of pepper jack cheese on top of the chicken layer. Place the top half of the rolls on the sliders.

Melt the butter and add the onion powder, garlic salt, and Worcestershire. Whisk together. Use a brush to cover the entire top and sides of the sliders with the butter mixture. Drizzle any leftover butter on the sliders. Sprinkle the sliders with sesame seeds.

Cover the sliders with aluminum foil and bake for 20 minutes. Serve warm.
