I usually purchase long beans from the grocery and they are super expensive, so I always have to settle with the usual green beans for any recipe. When the farmers market is around town, then I get to make a favorite vegetable dish: Sauteed long beans and squash! I have not tried freezing long beans. Next time around, I will try freezing some. Thanks for sharing, @papa-pepper!
If you have any space available to garden at all, you should really grow them. They are super easy and produce so well!
