In a large mixing bowl, combine the shredded or diced chicken and Greek yogurt. Stir until the chicken is well coated.
Add the finely diced celery, halved grapes, and chopped almonds to the mixture.
In a small bowl, whisk together the Dijon mustard, honey, and fresh lemon juice, then pour this dressing over the chicken mixture.
Stir the ingredients until everything is evenly combined. Season with salt and pepper to taste.
Take a lettuce leaf and spoon a generous amount of the chicken salad into the center.
Roll the leaf around the filling like a wrap or simply fold it over to secure the filling.
Repeat with the remaining lettuce leaves and chicken salad mixture.
Notes
Arrange the wraps on a serving platter and garnish with additional grapes or a sprinkle of chopped almonds for extra flair. Serve with lemon wedges for a refreshing touch.
