Combine shredded cooked chicken with sliced celery, mayonnaise, chicken broth, dried cranberries, and chopped red onion in a bowl. Mix until well coated and season with salt and pepper to taste.
Slice the apples into rounds approximately 1/4 inch thick. Remove cores and toss slices in a little lemon juice if preparing in advance.
Serve the chicken salad on top of apple slices or alongside, enjoying immediately for best freshness.
Notes
For added texture, sprinkle with chopped nuts like pecans or walnuts before serving.
