Essentially you ‘re-grow’ green onions after each use. I remembered as a kid, growing the roots on a potato in a cup of water  so I figured why not give this a try.

My wife and I used our green onions, then gave it a shot; sure enough, it worked:

I know it won’t last too many more times, but we’re now on the 3rd grow for this particular set of onions, and they still taste good.

Give it a try!

Have you tried something similar? We’d like to hear about it in the comments.
