Parsley is so much more than just a garnish, and this Green Lantern cocktail from Gourmet.com proves it.  Combining a whole cup of fresh pureed parsley leaves with lime juice, club soda, and a little sugar, the Green Lantern is a refreshing way to cool off on a hot summer’s day.  Serve it virgin, or add gin or vodka for a little kick.  You’ll start seeing parsley in a whole new light.
