Preheat oven to 400°F. Season the chicken breasts on both sides with salt, pepper, garlic powder, and paprika.
Roast for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F. Remove from the oven.
In a blender, blend your pickles, celery and onion with pickle juice.
Mix your chicken breasts while still hot with the stand mixer until it is very finely shredded.
In a large bowl, mix all ingredients and fold until well combined.
Add salt and pepper to taste.
