Combine all the ingredients except the psyllium husk and mix well. For a smoother batter, you can use a hand blender.
Let the dough rest for 20–40 minutes.
Add the psyllium husk and gently mix until combined.
Spread the dough evenly onto a baking sheet lined with parchment paper. Use wet hands to press and shape the dough.
Sprinkle with oregano, olives, and a little flaky salt, if you like.
Bake at 170 - 175 °C (fan oven) for 20–25 minutes.
You can mark out the 12 slices with a knife or pizza wheel before baking. Once baked, let the bread cool on a wire rack before cutting it into slices.
