A British takeaway has launched one of the world's unhealthiest pizzas - a deep fried MARS BAR calzone containing around 2,000 calories. Described as a ‘Glaswegian twist’ on the Italian food it is served with grated almonds on top of the pizza dough, caramel sauce and a scoop of chocolate ice cream. It is packed with Mars Bar chunks then cooked in batter and dubbed by locals as the Mars-gherita Pizza.
