Spray a pan with cooking spray and place tortillas on pan onto stove and heat on low while preparing the slaw.
Prepare the coleslaw (this should take a mere 2-3 minutes) by adding yogurt into a large mixing bowl. Add avocado oil, sumac, date syrup, Celtic salt, nuts/seeds and blueberries or dates.
Mix until well combined.
Add cruciferous mix (your blend of kale, cabbage or shredded cabbage/carrots) and mix until well coated.
Flip tortillas and cook for another minute or two.
Assemble taco: Start with heated tortilla, layer with 1/2 cup prepared yogurt slaw, then add fish and avocado chunks.
