Many people open a can of chickpeas and don’t use the whole can. So how do you store the leftover chickpeas? You should first remove the chickpeas from the can, rinse and drain them. Then, put them in an airtight container and drizzle with a little olive oil to keep the chickpeas moist. You can keep them in the refrigerator for about 5 days. If you need to store them for longer, then you can put them in the freezer. However, before putting in the freezer add a little bit of water to the chickpeas to keep them from getting freezer burn.
