Is this edible? It doesn't look edible to me, but it came in a package of arugula. I suppose it's not that weird to get a random weed in with your lettuce, but in all my years of buying lettuce, I've never had it happen before.
(Not that anybody cares, but in the background, you can see exactly what I put on my salad: feta crumbles, walnuts, and Bolthouse Farms Raspberry Merlot dressing. Yum.)
