Butter lettuce, grown hydroponically, is a great way to add green to your cold-weather menus. This quick and easy salad is so tasty that you can throw some leftover roast chicken on top and call it a meal. We use store-bought walnuts here; for The Dandelion's recipe for spiced walnuts, go to bonappetit.com/go/walnuts.
