While purveyors at the event are quite open with samples of their health-oriented products, The Seattle Times reported Sunday that obtaining a recipe for the vegetable concoctions is nearly impossible.

"We can't tell all our secrets," said Ted Harris, who was offering chicken-less cutlets called "Chick 'n Nuggets" at Saturday's event.

"We have a lot of competition out there."

Scott Myers, who was selling the soy-based cheese "Sheese" at the event, concurred with Harris' stance, saying the growth of the vegetarian and vegan food industry has been met with uncouth tactics.

"It's a pretty cutthroat business," Myers said.

In fact, the industry is so hot right now that nearly half of the thousands of people expected to attend the festival will not be vegetarians, Vegetarians of Washington Vice President Stewart Rose told the Times.
