The Mysterious Case of the Vanishing Veggie Burgers

Went to lunch at Jake’s today, and, much to the dismay of a vegetarian companion, they were out of veggie burgers. The kind waitress explained that the manufacturer they use is no longer making them. Once our herbivore friend had ordered a grilled cheese instead, he said that this is the third time he’s encountered the dearth of veggie burgers in Dallas. Someone else in our party pointed out that Kellogg recently purchased Gardenburger, which could have created distribution issues for restaurants and stores using their products (or, yikes, this). What gives? Anyone know where to find a good sans-meat burger?
