Combine the ground chicken, crushed Oreo cookies, cheddar cheese, ranch dressing, panko breadcrumbs, green onions, garlic powder, onion powder, salt, and pepper in a large bowl.

Divide the mixture into four portions and shape each into a round patty about ¾-inch thick.

Heat a grill or skillet over medium heat. Cook the patties for 5-6 minutes on each side until golden brown and internal temperature reaches 165°F.

Slice the hamburger buns in half and toast them cut-side down in the skillet for 1-2 minutes.

Assemble the sliders by placing a patty on each bun and adding your desired toppings.

Serve hot and fresh, ideally alongside crispy fries or a refreshing salad.
