Preheat your oven to 180°C / 355°F.

Make a "flax egg" by combining ground flaxseed and water in a bowl. Allow to sit for about 5 minutes.

In a large mixing bowl, mix together almond flour, flax egg and salt until a dough forms.

Place the dough on a piece of parchment paper, then cover it with another piece of parchment paper. Roll it out using a rolling pin or bottle to 1-2 mm (0.04-0.08 in) thickness.

Remove the top piece of parchment paper. If using any of the optional seasonings, sprinkle them over the flattened dough now. Press down gently using your hands so the seasoning sticks.

Cut dough into little squares using a knife.

Carefully transfer the piece of parchment paper with the dough on it to a baking sheet. Bake for 20 minutes or until golden brown and crispy. The ones on the edges might be done quicker - remove them from oven and let the middle ones continue baking until done.

Transfer crackers to a cooling rack and let cool completely before enjoying or storing.
