As meatless mains become, well, mainstream, we're seeing more interesting vegetables in produce aisles. Komatsuna is one; it's a leafy green that's rich in vitamins and minerals. Like kale, Brussels sprouts and cauliflower, it has a lot of flavor and can punch up everything from soup to pasta. Earthbound Farm
has just started selling a mix it calls Zen Blend, which includes komatsuna, baby spinach, baby kale, red pak choi and red mizuna. Eat it raw in salads; sauté it with garlic and olive oil and stir into pasta or serve as a side dish; or add a fistful to soup in the last five minutes of cooking.
