Allow the chicken to sit on the counter for 15 minutes.
Meanwhile, in a small bowl, whisk well all the dressing ingredients. Season the chicken with just a pinch of salt and pepper (remember, the dressing is salty too, so don't overseason it!).
Lightly grease the grill with a bit of olive oil and preheat over medium-high heat.
Grill the chicken breast until charred and no longer pink on the inside. Allow it to sit on a chopping board for 5 minutes, then slice it.
Meanwhile, in a large salad bowl, add the kale and ½ of the dressing. Massage the kale for a couple of minutes to tenderize the leaves.
Top with grilled chicken, crunchy celery, shaved parmesan, and the remaining dressing. Toss and serve.
