Begin by shredding your cooked rotisserie-style chicken, which will serve as the hearty base for your chicken salad. Transfer to a large bowl.

In a medium mixing bowl, whisk together mayonnaise, sour cream, white wine vinegar, and lemon juice until smooth. Season with sea salt and add optional sugar if desired.

Pour the dressing over the shredded chicken in your large bowl. Add the finely diced celery and white onion. Gently mix until each piece of chicken is coated.

Cover the bowl and refrigerate for at least 1 hour to allow flavors to meld.

Serve chilled in bowls or on greens. Works well in wraps or sandwiches.
