KFC’s new Nashville Hot Chicken is causing a stir in Nashville — and not necessarily for the reason the chicken chain wants. The restaurant’s latest chicken offering began selling nationwide on Monday. The new menu item is based on an iconic Nashville, Tennessee, dish and has been, according to KFC, the most successful product test in the company’s recent history. While the Hot Chicken was a hit when tested in Pittsburgh, some Tennesseans were less impressed, taking to social media to express their dismay.
