Start by cooking the chicken breasts in salted water until they are fully cooked.
Once cooked, shred the chicken into bite-sized pieces.
In a mixing bowl, combine the shredded chicken with mayonnaise, ranch seasoning, puréed celery, onion powder, garlic powder, celery salt, salt, and black pepper.
Mix everything together until well combined.
Serve the mixture piled high on a buttery croissant or alongside crackers for a simple and delicious lunch.
