I'm a fan of purslane, sorrel, and lamb's quarters myself. Not all weeds are bitter. Sorrel has a lovely lemon flavor and is good in salads. It helps to know when to pick something as many edible plants tend to become more bitter and tough with age. I find wild edibles fascinating. Why do we eat what we eat? What makes something a weed? Arugula is considered a weed in many places, but you can order it at fancy restaurants. I've even heard of purslane being sold at fancy places and it grows all over, even in sidewalk cracks, where I live. Oh, I also love wine berries, yum!
