In a large bowl, combine ground chicken, crushed Oreos, shredded cheddar cheese, and ranch dressing. Add panko breadcrumbs, sliced green onions, and seasonings. Mix together until well combined.

Divide the mixture into four portions and shape each into a round patty about ¾-inch thick. Refrigerate for about 10 minutes.

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

Split hamburger buns and toast them cut side down on the grill or skillet for 1-2 minutes until golden.

Assemble sliders by placing a patty on the bottom half of each bun and add your favorite toppings. Close with the top half of the bun.
