Place cashews in a glass jar. Add hot water and set aside for at least 15 minutes.
Drain the soaked cashews and add to a high-speed blender. Add the Dates, Applesauce, Mustard, Vinegar, Nutritional Yeast, and Garlic to the blender. Blend until completely smoothed.
Add the celery seeds to the sauce. Pulse briefly. Do not over blend the seeds as this will result in the sauce having a bitter taste.
Add the Kaleslaw to a large mixing bowl. Add the sauce and mix thoroughly using hands. Be sure to massage the Kale as mixing to help tenderize. Cover and chill for 2 hours to allow the Kale to wilt and the flavors to blend. Serve and Enjoy!
