Need a quick and easy weeknight dinner that's healthy and delicious? Salmon en Papillote with Edamame Mash full-fills all! En papillote is French for 'in parchment' (pronounced "ON poppy-YOTE"). It is a method of steaming that locks in flavor and moisture. It may look (and by name, even sound) fussy, but it couldn't be easier, and it's virtually foolproof.
