Preheat the oven to 350°F and line a baking sheet with parchment paper.

In a large bowl, combine the almond flour, coconut flour, garlic powder, salt, baking powder, and onion powder. Stir until evenly mixed.

In another bowl, whisk together the warm water, eggs, olive oil, and psyllium husk powder until slightly frothy.

Pour the wet mixture into the dry ingredients and stir gently until a smooth dough forms.

Knead the dough briefly with clean hands until well combined but still soft.

Transfer the dough to the prepared baking sheet and pat it into a flatbread shape about ¼ inch thick.

Bake for 15–20 minutes, until the edges are lightly golden and the flatbread feels firm to the touch.

Let cool slightly before slicing and serving warm.
