Thanks for the link. IIRC, quinoa is a grain that is considered a complete protein.
I posted a comment in the cooking thread, but for those here who don’t read that, lambsquarters is a wild form of quinoa. the last 2 years I’ve purposely let some go to seed in an unused corner of the garden, just so I could harvest the seeds.
Still working on a more efficient way to winnow them. I built a bucket thresh and a hand-cranked dehuller that both work on them, but the winnowing is tricky. Not to mention dusty!
