Bring a pot of water to a boil on the stove. Add in chicken and cook until internal temp reaches 165F. Once fully cooked, remove from pot and finely chop with a knife. Alternatively you can also pulse in a food processor.
Add chicken to a large mixing bowl with all remaining ingredients. Use a large rubber spatula to mix everything together. Add additional mayo to reach desired consistency, and adjust seasonings to taste.
Serve on sourdough, with crackers and carrot sticks, in a lettuce wrap, or in a small bowl with additional sides. Store in an airtight container in the fridge for up to 5 days.
Notes
You can also cook chicken in a crock pot on low for 6 hours, or roast in the oven for 25-30 minutes before chopping. I suggest using avocado-oil mayo, my favorite brand is Chosen Foods, but any one that uses only avocado oil (no seed oils).You can sub in whatever mix-ins you like! Grapes, apple, dried cranberries, raisins, celery, walnuts, pecans, etc.I love making this a curry chicken salad by adding in 1 tbsp curry powder and raisins instead of grapes.
