I haven't started growing stuff on purpose yet, but there's a good crop of nettles growing on the property where we're building a house. I picked a bunch a couple weeks ago and made enchiladas.
Phil, I saw a few pages back that you're wondering what to do with poblanos. I wish I could get poblanos (I did find something similar from a middle-eastern market). I used to roast them and use them as a base with tomatillos for veggie green chili. Works alright without the tomatillos, too.
