Supreme Master Ching Hai is a wacky gal. She believes there were once four planets called Venus, that crop circles are road signs for UFOs, and that the world's coming to an end unless you go vegan.The New Age guru may at least have the vegan thing pegged. That is, if you believe climatologists who argue that factory farming of animals for human consumption creates more greenhouse gases than all the world's cars, planes, trains, and buses combined.You don't have to buy all of Hai's teachings, or even revere her as the living Buddha, to enjoy her followers' vegan dishes at the restaurant chain she founded, Loving Hut, which has two locations in the Valley and serves up tasty Asian-fusion fare using faux shrimp, beef, and chicken made of soy or yam. The vegan carrot cake may even make a convert out of ya. Why, just by noshing it, you're helping to end global warming. Who knew going green would taste so sweet?
