Step 1: Prepare the Buffalo Chicken

1. In a medium-sized bowl, combine the shredded chicken, buffalo sauce, melted butter, garlic powder, onion powder, and paprika. Mix until the chicken is evenly coated in the sauce.
2. Warm the mixture in a skillet over medium heat for 3-5 minutes, or until heated through. Alternatively, you can microwave it in a microwave-safe bowl for 2-3 minutes.

Step 2: Assemble the Sliders

1. Preheat your oven to 350°F (175°C).
2. Slice the slider buns or Hawaiian rolls in half horizontally without separating them into individual rolls. Place the bottom halves on a baking sheet lined with parchment paper.
3. Spread the buffalo chicken mixture evenly across the bottom halves of the buns.
4. Top the chicken with half slices of cheese, ensuring each slider will have a gooey layer of melted cheese.
5. Drizzle ranch or blue cheese dressing over the cheese layer, and sprinkle with shredded lettuce, carrots, and red onions if desired.
6. Place the top halves of the buns over the filling.

Step 3: Add the Butter Topping

1. In a small bowl, mix the melted butter, dried parsley, and garlic powder.
2. Brush the butter mixture generously over the tops of the buns.

Step 4: Bake the Sliders

1. Cover the sliders with aluminum foil to prevent the tops from browning too quickly.
2. Bake in the preheated oven for 10 minutes.
3. Remove the foil and bake for an additional 5-8 minutes, or until the cheese is melted and the buns are golden brown.

Step 5: Serve

Remove the sliders from the oven and let them cool slightly before cutting into individual sandwiches. Serve warm with extra buffalo sauce and dressing on the side for dipping.
