> Samphire or Sea beans
Sounds yummy... some research later:
There are seeds: https://www.amazon.com/Davids-Garden-Seeds-Saltwort-Pollinated/dp/B0912PTS9D
And foraging possibilities: https://www.daringgourmet.com/wild-foraging-how-to-identify-harvest-and-prepare-sea-beans-sea-asparagus-samphire/
Although I bet my local Asian market has some in the produce aisle. I have the feeling I've seen it before.
Thank you, I learned something today.
