Ewa Michalik, author ofFood of Poland, and the owner of Patio, a Polish restaurant in west London, says we shouldn't be surprised: We cook a lot of cabbage, and we also eat a lot of beetroot, which has been forgotten as a vegetable over here. Poland's most famous vegetable dish, she says, is the kapusta - a salad Michalik makes from red and white cabbage, and accompanies with apples.
