KFC introduces 'sandwich' with buns made of CHICKEN instead of bread From a quick glance at the menu, a 'bunless chicken sandwich' might sound like the ideal meal for slimmers. Kentucky Fried Chicken is appealing to its carb-conscious customers by launching its first bread-free burger. But dieters may wish to look a little more closely at the picture on the left before they place their order. The traditional bun has actually been replaced with two thick slabs of fried chicken. The KFC 'Double Down', which goes on sale in the U.S. on Monday, contains two pieces of bacon and two melted slices of cheese, slathered in mayonnaise and sandwiched between two slices of meat. Nutritionists are horrified by the launch of the fatty dish in a country where two-thirds of the population is overweight or obese. KFC insists the sandwich contains 540 calories - but it has been reported that it actually racks up a much higher figure of 1,228, or about half of a man's recommended daily intake.
