Add the extra flour (and oats if you choose to) and transfer to a lightly floured surface and knead for 4-5 minutes. Separate into eight balls, shape into a pita pockets, and put on a oiled baking sheet. Let them rise in a warm place for thirty minutes.
Preheat oven to 450 degrees or higher for at least 10 minutes before baking. When time is up for the pita pockets bake them for 8 minutes flipping halfway through. Cool before cutting.
