Got it, so it's the "greens are a free action" thing. :-) This time of year we get chickweed, broad-leaf plantain, violet, dandelion, and lamb's quarters. Later we'll have lettuce and whatnot from the CSA, but I think I could be very happy on just weeds as greens.

Here, though, the lamb's quarters quickly becomes a tall woody plant without much good eating on it, so I largely try to suppress it in favor of the others.
