There's definitely more than one way to make a chicken salad sandwich, but this is our favorite—green apple, red onion, and celery add crunch, while mustard, mayo, and red wine vinegar add creaminess with the perfect amount of tang.
Step 1
In a large pot, arrange the chicken in a single layer. Place lemon slices and dill sprigs on chicken and pour water over it, covering by at least an inch. Bring water to a boil, then reduce heat and simmer until cooked through, 10 minutes. Let rest 10 minutes, then slice into 1" pieces.
Step 2
In a large bowl, combine chicken, apple, onion, and celery.
Step 3
In a medium bowl, whisk together mayonnaise, Dijon, and vinegar and season with salt and pepper.
Step 4
Pour dressing over chicken mixture and toss.
Step 5
Garnish with chopped dill and serve on a baguette with lettuce.
