KFC may be famous for its calorie-filled Double Down creation, but that may change.

The fast-food giant has announced a new burger made out of cauliflower and kale.

It features a "chia-seeded cauliflower bun", "unsweetened almond yoghurt", "ice cube relish", "spiralised chicken breast" and "100 percent British kale".

But things are not all as they seem, as it's suspected the burger is part of an elaborate publicity stunt aimed at trolling "clean-eating" fanatics.

The new dish has been created in collaboration with Figgy Poppleton-Rice - a so-called "#CleanEating fanatic and cauliflower connoisseur" - whose Instagram account first appeared only a week ago.
