Leaf vegetable
If leaves are cooked for food, they may be called boiled greens.  Leaf vegetables may be stir-fried, stewed, steamed, or eaten raw. Leaf vegetables cooked with pork is a traditional dish in soul food. They are also commonly eaten in a variety of South Asian dishes such as saag.  Many green leafy vegetables, such as lettuce or spinach, can also be eaten raw, for example in sandwiches or salads.
