A man who states he is a vegan is suing Burger King because the meatless Impossible Burger he purchased was cooked on the same grill as meat products.

In a class action lawsuit filed in the Southern District of Florida, plaintiff Phillip Williams claims the burger chain advertises its vegan option as meat-free, but it is contaminated by meat by-product left on the grill. Williams is accusing Burger King of false advertising - the Impossible Burger is touted as "100% Whopper, 0% Beef" - and benefiting monetarily from offering a vegan option that is not vegan.

According to Burger King's website, "guests looking for a meat-free option, a non-broiler method of preparation is available upon request."

Williams claims the drive-thru he visited in the Atlanta area did not note that the burger would be cooked alongside those containing meat and that if he had known he would not have bought it.

Williams claims he "suffered monetary damages in the amount that he paid to purchase" the Impossible Whopper.
