London (CNN Business) KFC is jumping on the meat-free bandwagon, launching a vegan version of its signature crispy chicken burger in the United Kingdom.

The fast food chain is calling its first plant-based offering "The Imposter." The burger, which uses a Quorn fillet and vegan mayo, will be sold at select restaurants for four weeks starting June 17.

Quorn is a meat substitute that gets its protein content from a fermented fungus. KFC describes the burger as "a triumph of deception."

KFC is the latest in a series of restaurant chains and food producers to attempt to capitalize on the public's growing appetite for meat alternatives.

KFC are testing a vegan item known as the "Imposter Burger."

Earlier this week, Burger King announced that they were expanding distribution of their popular meat-free burger Impossible Whopper to 100 locations in the San Francisco Bay Area.
