For one day only, the burger combines a fiery Zinger fillet with cheese, smothered in nacho jalapeno sauce and hot salsa, and a mac 'n' cheese parcel.

The burger was created by Reece Harrison, 21, who won KFC's own innovation challenge, which was open to all employees at the company.

The new treat is available exclusively in The Galleries Retail Park, in Tyne and Wear, and the firm has announced that a portion of all sales will be donated to Add Hope, the social responsibility trust.
