Instructions: Heat oven to 300 degrees.

Combine oats, barley flour, salt, water, and oil in a large bowl; mix throroughly.

Shape the dough into a rectangle and roll it paper-thin on a lightly greased, rimless baking sheet.

Moisten the surface of the rolled dough with a damp pastry brush, and sprinkle seeds on the dough. Roll again to press seeds into the surface.

Using a knife or pizza cutter, cut the dough into 1-inch squares.

Bake until thoroughly dry and slightly brown, about 40 minutes.
