In a large mixing bowl, combine ground chicken, crushed Oreo cookies, and cheddar cheese. Add ranch dressing, panko breadcrumbs, chopped green onions, garlic powder, onion powder, salt, and pepper. Mix thoroughly to create a uniform texture.

Preheat your grill or skillet over medium heat for about 5 minutes.

Place the shaped patties onto the preheated grill or skillet. Cook for approximately 5-6 minutes until a golden-brown crust forms, then flip and cook for another 5-6 minutes.

Add hamburger buns to the grill or skillet and toast for about 1-2 minutes until lightly browned.

Assemble each toasted bun with a cooked patty and add toppings as desired.

Serve the sliders hot with your favorite sides.
