In a large bowl, combine shredded chicken with chopped celery, mixing them together until evenly distributed.

In a separate bowl, whisk together mayo and Italian seasoning until smooth, then fold into the chicken mixture until well-coated.

Adjust seasoning as needed, tasting for balance—add salt or pepper for personal preference.

Let it chill in the fridge for at least 15 minutes before serving; this allows the flavors to meld beautifully.
