Shred or dice cooked chicken into a large mixing bowl.

Add diced celery, red onion, carrots, and green onions to the chicken.

In a small bowl, stir together Greek yogurt, blue cheese crumbles, ranch seasoning, and lemon juice until well combined.

Pour buffalo sauce over the chicken mixture and toss to coat evenly.

Fold in the dressing mixture until all ingredients are well incorporated. Season with salt and pepper to taste.

For best flavor, refrigerate for at least 30 minutes before serving.

Enjoy as a sandwich filling, in lettuce wraps, or on a bed of greens. Garnish with additional blue cheese crumbles and sliced green onions if desired.
