MIAMI — Burger King is teaming up with Unilever’s alternative meat business, The Vegetarian Butcher, to launch a new plant-based burger in Europe. The Rebel Whopper rolled out in more than 2,500 locations in 25 countries this week, the companies said.

Unilever acquired The Vegetarian Butcher last year. Its portfolio includes vegan hot dogs, meatballs, tuna, bacon, sausage rolls, bratwurst and several varieties of plant-based chicken. The main ingredients in the company’s plant-based burger are soy, wheat, vegetable oil, herbs and onion, Unilever said.

The announcement comes just months after Burger U.S. announced it is expanding the Impossible Burger nationwide.

“We are confident that the Rebel Whopper, powered by The Vegetarian Butcher, is the sandwich everyone has been waiting for and provides the ultimate plant-based patty alternative with the iconic Whopper build,” said David Shear, president of Burger King Middle East, Europe and Africa. “I’m excited to let the Rebel Whopper do the talking and see whether our guests can tell the difference.”
