Because green beans are high in fiber and water, they are low in calories with one-half cup serving furnishing only 22 calories. Green beans are naturally low in sodium. To take advantage of this, flavor green beans with basil, dill, marjoram, mint, oregano or thyme. Well-shaped pods with small seeds are desirable.
Length is unimportant.
Green beans should feel pliable and velvety, not hard or tough. Newer varieties of green beans are more tender and do not require as long a cooking period as the older varieties. This will preserve the bright green color. Cover and cook until just tender crisp. One pound of crosscut green beans will be ready to serve in 13 to 15 minutes.
