Green or string beans, a favorite side dish all year round, are particularly bountiful during their harvest in summer. Snap off the side with the stalk and serve them alone steamed with butter, salt and pepper, or add them to salads and soups. The finer haricots verts are perfect for a Nicoise salad with their elegant looks, tender texture, and sweet taste. Avoid any green beans that look dried out and use them quickly as they don't keep long.
