Pizza Express has launched a competition, allowing consumers to design the next pizza to be implemented on the half a century-old brand’s menu. The food chain, founded in 1965, will celebrate its 50th birthday on Friday 23 March and to celebrate, will launch the ‘Create Your New Favourite’ competition. The initiative will enable pizza fans to develop their own preferred topping combinations with the winning entrant rewarded with a £10,000 cash prize and a holiday.
