Green Beans with Garlic and Mint Dressing

Green beans are sold two ways: hand-picked or machine-picked. The hand-picked beans are usually sold in punnets and cost at least twice as much, but they’re worth it; often labelled baby beans, they’re small, straight and tender. Roman beans, also known as Italian flat beans, are long wide green beans that are eaten pod and all. The quicker you cook green beans the better they’ll keep their colour, so it’s important to use plenty of water and return it to the boil as quickly as possible. Sa
