Sure, green onions are cheap at the store and free in your garden, but in the winter this is going to come in really handy. I often want to throw in some green onions into dishes for a little flavour but usually don't have them on hand since they go wilty so quickly.
Here's what you do:
After using your green onions, keep the roots & white parts (with a little green still), stick them in a glass of water in a sunny place and watch them grow. You can snip them any time and they'll just keep coming back. Change the water occasionally. I've had mine going and using it here and there for about a month now! They grow back super quickly, too!
