In a medium mixing bowl, combine the poached & diced chicken, walnuts, apples, cranberries, and celery.
In a small mixing bowl, whisk together avocado oil mayo, red wine vinegar, dijon, lemon juice, and the seasonings, then add it to the mixing bowl with the chicken.
Stir everything until it's combined and mixed well. Taste and add more salt or seasonings if desired.
Top with some rosemary or dried sage, and serve on some lettuce boats or whatever you'd like!
