Add the chicken, 1/2 cup of mayonnaise, celery, grapes, pecans, onion, parsley, salt, and pepper to a mixing bowl and stir well to combine.
Add additional mayonnaise if you'd like a wetter consistency.
Store covered in the fridge for 1 hour to allow the flavors to meld before serving.
Divide evenly between 4 croissants.

Notes
Storage: Store leftovers in the fridge, tightly covered, for up to 5 days. This one is perfect for meal prep!Mayo: Not a fan of mayo? Try our Greek yogurt chicken salad instead. Super similar to this recipe but no mayo! Serving: Huge fan of croissants, but this is also delicious on white bread, toast, as a dip for crackers, and yes - even just eaten plain with a fork!
