KFC Is Selling A Taco With A Shell Made Out Of Fried Chicken Because Dreams Do Come True. KFC continues to render the laws of typical food irrelevant. First, the brand made a sandwich with fried chicken for buns (ah, the Double Down...), recently it made chicken sandwich with donuts for buns, and now, at least in Singapore, it's innovating in a way we never saw coming: a taco with a fried chicken "shell." This is amazing and I want one!!!!
