This is a meatless version of the traditional Logo Petse, as it is served at the Lhasa Moon, a Tibetan Restaurant, located in San Francisco. Some cooking notes: use the standard head cabbage, which is the type grown in Tibet. As for the spicing used in this recipe, according to the Tibetan chef at the Tibet Nepal House (our favorite Himalayan restaurant), Tibetan cuisine is the least spiced of the Himalayan cuisines. If one wishes to add seasonings, some that are common to Himalayan cuisine include - black and white cardamom, Jimbu, garlic, ginger, cumin, coriander, nutmeg, cinnamon, Ajwain, star anis, Timboor, chili, turmeric, saffron, sesame seed and mustard seed.
