It will be part of a sandwich called The Beyond Famous Star burger ( $6.29) - a veggie version of the brand's flagship Famous Star.
The patty is part of a build featuring cheese, lettuce, tomato, sliced onion, dill pickle, special sauce, and mayonnaise. If ordered without the cheese and mayo, the sandwich is suitable for vegans.
Vegan, vegetarian, flexitarian
"We know people are looking for options - in fact, roughly one-third of consumers identify as flexitarians - and we're thrilled to partner with Beyond Meat to bring more delicious, irresistible flavors to our menu," Jason Marker, CEO of Carl's Jr. parent company CKE Restaurants, said in a statement.
"The new Beyond Famous Star is a true industry game-changer, and we're proud to add it to our roster of innovative offerings and build on the legacy of mouthwatering flavors."
Vegan fast food
"I have long looked forward to the day when my kids can go to a major fast-food chain and order the Beyond Burger," Beyond Meat CEO, Ethan Brown, added. "I am grateful to say that that day has arrived.
"At our core, Beyond Meat is about enabling consumers to 'Eat What You Love,' and there is no better example than being able to enjoy a delicious Carl's Jr. burger, while receiving the added health and sustainability benefits of the plant-based Beyond Burger.
