Also known as string beans, runner beans are a summer staple, grown in many people’s gardens. Eaten fresh, they can be a delight. If they’re a little on the old side, they may need de-stringing or chopping finely. Use them liberally in stir fries, create a green risotto along with other beans and pulses, or simply boil them to have alongside your main course. If you have a glut, they make a wonderful chutney.
