Store leftover chickpea flour tortillas in the freezer for up to 3 months. To do so, transfer them to a zip-top bag or sealed container, placing a sheet of parchment paper in between each layer to prevent them from sticking together. To reheat, place them on a large plate, then cover with a damp paper towel. Microwave for 20-30 seconds, or until they are thoroughly heated. You can also warm them on stove in a heated pan for 1-2 minutes on each side. I do not recommend storing them in the fridge as they will dry out pretty easily, causing them to be fragile and break easily.
