Burger King announced on Monday that it is testing out Impossible Whoppers, made with plant-based patties from Impossible Foods, in 59 locations in and around St. Louis area.

While McDonald's is waiting to jump into plant-based meat substitutes, Burger King is reaping the rewards for taking the plunge.

On April 1, the Restaurant Brands International chain announced it was testing a vegetarian friendly version of its Whopper, made with the plant-based Impossible Burger, which is known for "bleeding" just like a real burger patty. Before the month ended, Burger King said it would launch the product nationwide this year. It has since brought the Impossible Whopper to three more cities.
