Big thanks to Nick Burtner at School of Permaculture (https://schoolofpermaculture.com) for posting about this plant being edible on Facebook.
Been growing it for years and never knew it was that type of resource. The seeds are pretty good raw, I would say adding them to salads would be a good use, I am going to try toasting them gently to crisp them up a bit and bring out more flavor, when I do I will report back to you guys on the results.
Also here is a video by Green Dean on using this plant for edible purposes. https://www.youtube.com/watch?v=sKy6Ivh0HaE
