Shred the cooked chicken into bite-sized pieces using two forks or your hands.
In a large mixing bowl, whisk together the Greek yogurt and buffalo wing sauce until smooth and well combined.
Add the shredded chicken, diced celery, diced red onion, and shredded carrots to the bowl. Toss gently until all ingredients are evenly coated with the dressing.
If using, fold in the crumbled blue cheese. Season with salt and pepper to taste. Remember that the buffalo sauce adds saltiness, so go easy on the salt.
Cover the bowl with plastic wrap or a lid and refrigerate for at least 30 minutes to allow the flavors to meld. The salad can be made up to a day ahead.
Serve chilled or at room temperature in lettuce cups, on whole wheat wraps, or with crackers. Enjoy!
