Onions

Onions are another vegetable that can be easily grown from scraps. Simply cut off the root end of the onion leaving only a small amount of the onion flesh attached. Plant this just beneath the surface of the soil in a sunny location, and in a few months you should have a new onion, reports the San Francisco Chronicle. You'll know the onion is ready when its stalk starts to turn yellow.

After eating your onion, plant its roots in the ground again and you'll be able to check one more item off your future grocery list.
