Pad Thai stores wonderfully in an airtight container in the refrigerator for up to 5 days. Reheat in the microwave or in a pan on the stovetop. You may want to add a bit more sesame oil to loosen up the rice noodles. You can also freeze this vegan Pad Thai. Let cool to room temperature, then freeze in a freezer-safe container for up to 3 months. Let defrost in the refrigerator overnight, then reheat.
