Preheat oven to 350F and line a 13x9 baking pan with parchment paper draped over the sides. Set aside.
Combine flax seed with baking powder, herb mix and sea salt in a large bowl. Whisk to combine fully and set aside.
Add eggs, water and oil to the jug of your high-powered blender. Blend on high for 30 seconds, until foamy.
Transfer liquid mixture to the bowl with the flaxseed mixture. Stir with a spatula, just until incorporated. The mixture will be very fluffy. Once incorporated, allow to sit for 3 minutes.
Drop mixture into prepared baking pan. Smooth with the back of the spatula and transfer the pan to the preheated oven.
Bake bread for 20 minutes, until top is golden. Remove from the oven and lift bread (from the parchment paper sides) to a cooling rack. Peel the parchment paper from the bottom of the bread and allow the bread to cool on the cooling rack for an hour.
Cut into 12 pieces.
Bread can be toasted or frozen. Keeps in the fridge for 3-4 days and in the freezer for up to 3 months.
