In a bowl, combine the two flours and salt.

Create a well in the center of the flour and add a tablespoon at a time, stirring until a sticky dough forms.

Use the oat flour to dust a flat surface. Knead and work the dough until a smooth ball forms.

Gently roll out or use your hands to stretch out the dough into a small rectangle (or circle).

Trim any rough edges if making a rectangular flatbread.

Baste and season the flatbread with olive oil.

Sprinkle with salt (optional).

Place on a preheated pizza stone and bake at 400 for 10 minutes.

Temporarily remove flatbread and proceed to add toppings of choice.

Place the flatbread back in the oven for an additional 5-8 minutes or until toppings are warmed and cheese is melted.
