Thailand's veggie festival has roots in Chinese legend

Thailand is not an easy country in which to be vegetarian. But once a year the country's avid meat eaters lay down their spicy meat stir-fries in favor of vegetables and meat substitutes.

During the annual 10-day "Tesagin Kin Pak" vegetarian festival, yellow flags representing Buddhism and good moral conduct flutter in the wind above entire neighborhoods, while tiny mobile street carts with a lone yellow flag advertise vegetarian-friendly food.

Glistening tofu, noodles with bean sprouts, desserts made with sesame and ginger, and steaming hot vegetable broths abound.
