Which item is considered Bojangles' signature food offering?

The Cajun Chicken Biscuit is considered Bojangles' signature food offering because it embodies the brand’s Southern roots and is a standout item on their menu. It features a spicy, seasoned chicken fillet served on a freshly baked biscuit, which is known for its flaky and buttery texture. This dish reflects Bojangles' focus on flavorful, hearty meals often associated with Southern cuisine, particularly the emphasis on biscuits and fried chicken.

Other items in the list, such as fish tacos, BBQ ribs, and garden salad, do not represent the core offerings that define Bojangles' mission and identity in the fast-food industry. These alternatives may not carry the same cultural or brand significance as the Cajun Chicken Biscuit, which has become synonymous with the variety and zest of Bojangles' culinary approach.
