I have a large pigweed (amaranth?)growing in one of the garden beds, very healthy & a good sized lambs quarter just on the edge of a path. Since it has amused me to leave them there & I have been using the branches to shade the tomatoes. I picked a mess of leaves & boiled with chicken bullion. As good as any spinach or any other green Ive tried save for beet greens, always the best. we also have lots of purslane, I think it is eaten raw in salad? What do you think?
