Season the chicken cutlets with lemon-pepper seasoning blend, and grill until cooked through. Alternately, you can start with cooked frozen chicken cutlets and just thaw them.
Cut the chicken into ½” cubes.
In a small bowl, combine the mayo and lemon juice to form the dressing.
Add the chopped celery, chopped onion, and cubed chicken. Toss to coat.
Serve on your favorite bread to make a sandwich, or as is with a side of crackers. Makes 2-3 servings.
