If freezing, place in a freezer bag with a piece of baking parchment between each pita (to stop them sticking together). Defrost at room temperate before serving. Reheating: The flatbreads can be served at room temperature, or if you want to warm them through, sprinkle with a little water and place in the oven at 180C (350F), on a baking tray (uncovered), in a single layer for 2-3 minutes.
