Lambsquarters

I kind of want to try lambsquarters.
They are supposed to be quite nutritious. However, I am scared to pick something that will poison me, which is why I will probably never pick wild mushrooms to eat. I have some friends who know how to identify all those plants; they used to do it for a living in Washington State, and now, how lucky, they are in Northern Virginia. I shall have to ask them to take me on an edible foods nature walk.
