Farm Sanctuary prompted Burger King franchise owner David Kessler to bring a veggie burger to customers in western New York in 1993. Mr. Kessler said that getting corporate approval for his request to test market the Griller "was like turning the around in a bathtub", but that he was able to prove that the veggie burger was very popular. In March 2002, Burger King announced it was adding a veggie burger nationwide to its permanent menu, with Morningstar Farms as its sole supplier.
