KFC Double Down
Forget letting the bun get in the way of your chicken - with KFC's Double Down, the chicken is the bun. Two fried or grilled chicken breasts bracket bacon and cheese.
Walter Willett, chairman of the nutrition department at the Harvard School of Public Health, marveled at the 1,380 milligrams of sodium packed into the Double Down (the recommended daily limit for adults is 1,500 milligrams). And Florida-based blogger Jason Kelley of foodgeekery.com called the product "perhaps the most insane 'sandwich' I have ever seen."
