Green onions are easy to re-grow. After you use them up, save the bottom part. Just stick them into some water and they will re-grow. Give them fresh water every few days. The green onions can be planted in the soil outside but you can also just keep them in your kitchen and keep re-growing them. This will give you an endless supply. LINK
