Pour the chicken broth into a crock pot and add the shredded chicken.
Place the onion and celery into a high speed blender (I use a Vitamix) and add the coconut milk and tapioca flour. Blend on high speed until everything is pureed. Pour the mixture into the crockpot.
Add the carrot, peas, garlic, salt, pepper, and sage. Stir everything until it is combined.
Program the crock pot to high. Cook on high for 4 hours or program the crockpot to low and cook on low for 6 hours.
