Start by cooking the chicken. In a medium pot, boil water and add the chicken breasts. Cook for about 15-20 minutes or until fully cooked. Remove from water and let it cool before shredding.
In a large mixing bowl, combine the shredded chicken, diced celery, halved grapes, sliced almonds, and finely chopped red onion.
In a separate small bowl, mix together the mayonnaise, Dijon mustard, lemon juice, salt, and pepper to create the dressing.
Pour the dressing over the chicken and vegetable mixture. Stir gently until everything is well coated.
Taste and adjust seasoning with more salt and pepper if needed.
Serve the chicken salad on a bed of lettuce leaves if desired, or on its own.
Feel free to swap grapes for apples or dried fruits for different flavors.
You can also add chopped herbs like parsley or dill for an extra layer of taste.
To make this salad healthier, consider using Greek yogurt instead of mayonnaise.
