In the bowl of a food processor or mixer that you will eventually mix everything in add the flax meal and water. Do this first and allow it to soak.
While the water and flax meal are soaking, add the dry ingredients to a separate bowl. Mix together the protein powder, husk powder, baking soda, and sea salt. Set aside.
In the same bowl as the soaked flax meal, add the eggs, apple cider vinegar, and tahini or nut butter.
Add dry ingredients to wet ingredients.
The dough will be very sticky and come together in a ball. Spoon into a greased loaf pan lined with parchment paper. If you want a smoother top crust, wet your hands and pat the top of the loaf smooth. I sprinkled my loaf with sesame seeds!
Bake at 400° for 30-35 minutes.
