Step 1: In a large mixing bowl, combine the shredded or diced cooked turkey, chopped celery, and minced red onion. If using, add any optional crunchy elements like nuts or dried fruit.
Step 2: In a separate small bowl, whisk together the mayonnaise, Dijon mustard, apple cider vinegar (if using), dried tarragon (if using), salt, and black pepper. Taste and adjust seasonings as desired.
Step 3: Pour the prepared dressing over the turkey mixture. Gently fold everything together with a spatula or large spoon until all ingredients are well coated and evenly distributed.
Step 4: Cover the bowl and refrigerate the turkey salad for at least 30 minutes, or preferably an hour, to allow the flavors to meld and chill thoroughly. This step is crucial for the best taste.
Step 5: Serve chilled on your choice of bread (sourdough, croissant, whole wheat), in lettuce wraps, with crackers, or as a topping for a fresh green salad. Enjoy your freshly made turkey salad recipe!
