Washington | Burger King, whose quarter-pound Whopper pushed its competitors a half-century ago to create their own two-fisted hamburgers, now plans to roll out a vegetarian version of its signature sandwich, relying on plant-based patties developed by San Francisco Bay area start-up Impossible Foods.
The Impossible Whopper will be introduced this week at Burger King restaurants in the St Louis, Missouri, area - in the very state that last year banned the use of the term "meat" for any vegetarian or cell-based substitutes for animal-raised meats.
