These leafy greens are a popular Chinese vegetable from the cabbage family. Pak choi has paddle-shaped dark green crisp and crunchy leaves with a thick creamy stalk and a mild flavour. Pak choi is served cooked and both the leaves and stalk can be eaten. It can be served as an accompanying vegetable or included in vegetable, meat or fish stir-fries. To prepare wash thoroughly and trim the stalk and slice it into slightly smaller pieces. If stir-frying pak choi trim the leaves into even-sized pieces.
