1. Combine apple and lemon juice in a large bowl; toss well to coat apple. Add chicken, celery, and raisins; toss well.
2. Combine mayonnaise and next 5 ingredients in a small bowl; pour over chicken mixture, and toss well. Sprinkle with chopped almonds. Cover and chill at least 1 hour.
Note: If you don't have 3 cups of leftover chicken, cook 1 pound of skinned, boned chicken breast halves on a baking sheet in the oven at 450° for 12 to 14 minutes or until the juices run clear. Toast the almonds on the same baking sheet during the last 3 minutes of cooking.
