Ever found onions sprouting in your pantry? Don't toss them! Even though the eating quality of onions decline as they begin sprouting, you can place the ends of the onion bulbs in a little water and regrow some onion leaves! They can be eaten just as spring onions. Yum! :)Here's the growing stages of what my roomies and I call our mini "onion farm". I thought our onions looked a bit lonely so I bought a pot of organic basil and celery stalks to join the family.
