Ingredients
  

Main Ingredients
  • 3 pounds cooked rotisserie-style chicken (shredded)
  • 0.5 cup mayonnaise
  • 0.5 cup sour cream (use dairy-free if needed)
  • 2 tablespoons white wine vinegar
  • 0.5 lemon (juiced, about 1 tablespoon)
  • 0.5 teaspoon sea salt
  • 2 teaspoons sugar (optional for sugar-free diets)
  • 6 ribs celery (finely diced)
  • 0.5 white onion (finely diced)

Method
 

Preparation
  1. Begin by shredding your cooked chicken. If you have a food processor, pulse the chicken in small batches for finer texture. Otherwise, use two forks or chop finely with a knife. Place the shredded chicken in a large bowl and set it aside.
  2. In a medium bowl, whisk together mayonnaise, sour cream, white wine vinegar, and lemon juice. Add salt and sugar, and stir until smooth.
  3. Pour the dressing over the shredded chicken. Gently add the diced celery and onion. Mix everything thoroughly until the dressing is evenly distributed.
  4. Refrigerate the salad for at least an hour to allow the flavors to meld. Serve it cold.

Notes

Feel free to use fresh herbs and adjust the ingredients based on what you have on hand. The recipe is flexible, and leftovers can last about 3-5 days in the fridge.
