                You might run across purslane, with its glossy, plump leaves, at a farmers marketand you might even find it growing in the cracks of your sidewalk or in your yard. Luckily, this incredibly nutritious and juicy green is a weed, which means it pops up wild nearly everywhere. Lots of chopped parsley and a simple vinaigrette flatter its herbal, lemony crunch.
