In a large mixing bowl, combine the ground chicken, panko breadcrumbs, egg, scallions, parsley, salt, pepper, garlic powder, dill, and 2 tablespoons of wing sauce. Mix everything together with a fork until well combined. Shape the mixture into four equal patties and place them on a platter or cutting board.
Optional/Recommended: Cover and refrigerate for at least an hour to allow the flavors to meld and the patties to firm up.
When ready to cook, lightly coat a nonstick grill pan or skillet with cooking spray and heat over medium. Cook the burger patties for about 5 minutes on one side, then flip and cook for an additional 5 minutes until fully cooked through.
While the burgers are cooking, mix the dry coleslaw mix with blue cheese dressing in a separate bowl until well coated.
To assemble, place a lettuce leaf on the bottom half of each bun. Add the cooked burger patty, drizzle with a teaspoon of Buffalo wing sauce, then top with ¼ cup of the blue cheese coleslaw. Finish with the top half of the bun.
