Drain the canned chicken breast thoroughly and flake into a large mixing bowl using a fork.

Combine the avocado oil mayonnaise, lemon juice, salt, and black pepper in a small container, whisking until smooth.

Add the diced celery, sliced green onions, unsweetened dried cranberries, and chopped pecans to the chicken.

Pour the mayonnaise dressing over the chicken mixture and fold gently until all ingredients are evenly coated.

Serve immediately or store in an airtight container for up to 4 days.
