peta spokesperson pamela anderson joined forces with arizona sheriff joe arpaio to promote the benefits of a vegetarian diet for prisoners .
arpaio says cutting meat from the meals served to the more than 8,000 inmates has saved an estimated $ 200,000 per year .
reporters on a previous visit to the prison discovered the carrots in the stew were brown and that the soy looked like ` wood chips '
the pr stunt at maricopa county jail on wednesday has been described as ` a new low for peta '
arpaio is better known for his controversial opinions and racial profiling of latinos , than his dedication to a vegetarian diet .
