Combine all the dry ingredients in a bowl: cassava flour, tapioca starch, brown rice flour, psyllium husk, baking powder and salt. Drizzle in some olive oil and then start slowly to pour in the hot water.
Fold together until the dough becomes tender yet firm. Slice the dough into equal sized quarters, then cover the bowl with a damp cloth.
Lay some parchment paper on your countertop and place the dough balls on the paper. Dust a little bit of cassava flour on a rolling pin and roll the dough flat.
Drizzle a touch of olive oil into a pan or cast iron skillet over medium high heat and cook for about 2 minutes on each side until golden brown.
