On Thursday, Burger King restaurants are mixing up the popular 2 for $6 promotion, now with the Impossible Whopper sandwich. Available for a limited time only, guests can choose between the Impossible Whopper, Spicy Crispy Chicken, Crispy Chicken, and Whopper sandwich.

“We are excited to offer our guests a plant-based product like the Impossible Whopper as part of our 2 for $6 promotion,” says Chris Finazzo, president, North America, Burger King Corporation. “This unbeatable deal gives friends and family a new reason to come in and try the Impossible Whopper and other BK favorites at an amazing value.”

Burger King restaurants rolled out the Impossible Whopper sandwich with a patty made from plants nationwide last year following a successful test in St. Louis and six other markets across the U.S. The offering made Burger King restaurants the first coast-to-coast quick-service restaurant to serve the award-winning, plant-based meat from food startup Impossible Foods, maker of the Impossible Burger.

The Impossible Whopper features a flame-grilled patty made from plants topped with freshly sliced tomatoes and onions, crisp lettuce, creamy mayonnaise, ketchup and zesty pickles on a toasted sesame seed bun.

Guests can visit their local restaurant and decide for themselves if the Impossible Whopper delivers the same flame-grilled, juicy craveability of the famous Burger King restaurants Whopper sandwich.
