In a large bowl, toss prepared chicken bites with the cayenne pepper sauce. Heat oil in an extra large skillet or Dutch oven. Cook chicken, celery, and onion in hot oil for 3 minutes or until vegetables are tender. Meanwhile, in a medium sized bowl, combine the Marzetti Mayonnaise, milk, Marzetti Chunky Blue Cheese Salad Dressing, and 2 tablespoons of the blue cheese crumbles. Add dressing mixture and thawed pasta to skillet with chicken mixture. Cook over medium heat, stirring constantly until heated through. If desired, serve with remaining 2 tablespoons blue cheese crumbles sprinkled over top. *Or use frozen fully cooked breaded chicken breast nuggets or strips (cut strips into bite size pieces)
