Agreed, it looked like he was peeling off way more than necessary. I've had them raw, never cooked, but it looks like they would be a fun veggie to put on the table.
Dang, I just did a search for 'edible weeds in Kansas' and found a long list! Try it for your state.
There are more edible things around here than I thought. I won't gather anything that's next to the road because of car exhaust. Unfortunately, some things that I want, I haven't spotted, like elderberry.
my concern with almost any wetland or river foraging around here is the agricultural poisons. cattails are in many ditches, but those ditches are runoff from heavily sprayed fields. the same with all the rivers.
if i can't grow it or know that the area hasn't been used for agriculture i won't harvest from there. too many poisons being used and some persist for a long time.
