Herbal and earthy, firm and crisp, green beans are universal favorites, and these pretrimmed versions make weekday dinner preparation a snap. They're a classic side dish served on their own — simply steam, sauté, or boil them (we like to add a little butter and lemon). Their texture also stands up to long cooking in dishes like casseroles and stews, or for a lightning-fast vegetable side, simply microwave them.
