1Preheat an outdoor grill for medium-high heat, and lightly oil the grate. Stir the sour cream, blue cheese, and Worcestershire sauce together in a small bowl; set aside.
2Mix the ground chicken, 1/4 cup hot sauce, celery salt, poultry seasoning, paprika, and cayenne pepper together in a mixing bowl until evenly blended. Form into four 3/4-inch-thick patties.
3Cook the chicken burgers on the preheated grill 6 to 7 minutes until well marked. Spray the uncooked top of the burger with cooking spray, and flip the burgers over. Brush the cooked side with 1 tablespoon hot sauce, and continue cooking until no longer pink in the center and the juices run clear, about 5 minutes more. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
4To assemble the burgers, place a lettuce leaf on each roll bottom. Top with a burger patty, then spoon on 2 tablespoons of blue cheese sauce, and 2 tablespoons celery. Place the top of the roll on top to finish the sandwich.
