Storing your delicious General Tso Cauliflower is easy. To retain its flavor and texture, it's best to keep the dish in an airtight container in the refrigerator. It should stay fresh for up to three days, but it's best to eat it sooner rather than later. You can also freeze the dish in an airtight container for up to two months. When you're ready to eat it, thaw in the refrigerator overnight and warm on the stove or in the oven before serving.
