Wild edible "weeds" - PURSLANE

Have been finding it along most sidewalks by the curb, purslane, which is edible. Remember if you decide to try sampling any plant growing around, double triple check its id. Recall talking with someone who gave a lift to a hitchhiker who was so excited to share what he found. Wild carrots, but the person who teaches classes in wild edible plants, informed him to wash his hands and toss the stuff as was hemlock, and quite poisonous.
Next, dont eat something on side of road due to toxins from gas,brake dust....  dog feces....
Purslane , if recall what read as a child (checked all the wild edible plant books out of the library ), it could be eaten raw in a salad or cooked, someone had a recipe with bacon for the purslane. It almost is a succulent like plant, on the bland side.
  Purslane heard in last few years also has omega 3 fatty acids, which posibly some people need more of.
Not everyone can access the omega 3's from purslane, (forget if a genetic thing or what ).  Also wonder if in the leaves or seeds. The seeds are like poppy seeds and the plant has quite a few (as can attest to many new little plants in my front yard.
