It will launch in Tennessee and North Carolina in March ahead of a nationwide rollout. Several fast food chains have introduced chicken sandwiches to compete with Chick-fil-A and Popeyes. Taco Bell is becoming an unexpected participant in the chicken sandwich wars with a new Crispy Chicken Sandwich Taco. The hybrid menu item will first be available in Nashville, Tennessee and Charlotte, North Carolina beginning March 11, with a planned nation-wide rollout later this year. The Sandwich Tacos will retail for $2.49.
