In a large bowl, combine the diced chicken, celery, green onions, shredded carrot, and chopped red bell pepper.
In a separate bowl, whisk together the Greek yogurt, Buffalo sauce, garlic powder, salt, and pepper, until well combined. Pour the dressing over the chicken mixture and toss to coat evenly.
Serve as a filling for sandwiches, inside lettuce cups, as a dip with crackers, or in a wrap. If desired, sprinkle with crumbled blue cheese prior to serving.
