Preheat oven to 350 degrees F. Prep a baking sheet with parchment paper. Combine psyllium husk powder and water and whisk immediately. It will thicken up right away. Set aside for 10 minutes.
Combine all the dry ingredients (except everything seasoning) in a large bowl if you're kneading by hand or using a hand mixer. I used a kitchen aid mixer with the dough hook. Mix together.
Pour the psyllium husk mixture into the dry ingredients. It will take 5-10 minutes for the dough to form. If the dough is too sticky/wet, add 1-2 tablespoon chickpea flour. If it feels too dry, add 1-2 tablespoons water.
Shape the dough into the bread shape you want (I did round). Sprinkle with everything seasoning.
Bake for 60 minutes. Remove from the oven and let it cool completely before cutting into it.
Notes
This bread freezes well
Keep in a container or sealed bag on the counter or the fridge.
Substitute flours at your own risk - this bread is very finicky as it's both vegan and gluten-free. Changes the flours will change the recipe significantly.
