Dallas is nary in short supply of meat-based celebrations. If it used to be slowly moving and has since been brought to an internal temperature of 150 degrees, then the great citizens of DFW have no doubt booked a venue, reserved a cover band and thrown a party in its honor. But there will be one festival this Saturday where the only meat you are likely to see is on the front of someone's "Meat is Murder" T-shirt. The annual Texas Veggie Fair at Reverchon Park aims to promote the veg-lifestyle by featuring vegetarian and vegan food vendors, chef demonstrations, a beer garden and yoga. So go, hippies, go. Tempeh samples await.
