A Florida man is suing Burger King after discovering his meatless Impossible Whopper was cooked on the same grill as regular beef patties.
The Impossible Whopper is sold as a plant-based, meat-free alternative to regular beef patties at Burger King in the US, instead made from textured wheat protein, potato protein and other vegan ingredients.
The tagline for the burger is '100 percent Whopper, 0 percent Beef'.
Phillip Williams lives a vegan lifestyle, meaning he eats no food made with animal by-products.
In a lawsuit against Burger King, Williams claims he was "duped" by the company, after learning the Impossible Whopper is cooked on the same grill as the rest of Burger King's meat products.
According to The Guardian, Williams claims it meant his vegan burger alternative was "covered in meat by-products".
"For guests looking for a meat-free option, a non-broiler method of preparation is available upon request," the Burger King website notes. However, Williams says there was no signage explaining that on his trip through the Drive-Thru, nor was he told by any staff members.
The Impossible Burger is not yet for sale at Burger King in New Zealand. Burger Fuel has an alternative, made from competing brand Beyond Meat.
Newshub has asked Burger Fuel for comment on the cooking methods of their burgers in Aotearoa.
