In a medium bowl, combine the yogurt, buffalo sauce, milk, lemon juice, seasoned salt, pepper, garlic and onion powders, chives, and parsley. Stir until well combined. Stir in chicken, celery and cabbage.
Serve in lettuce cups, stuffed in a pita pocket, or scoop with your favorite crackers. Top with blue cheese crumbles if desired. Refrigerate until ready to serve. Best after it has chilled for at least an hour to allow for flavors to combine.
