The new Chik-fil-A Chicken Salad Sandwich is proving to be a successful menu item. On May 19, Chick-fil-A introduced the most aggressive menu enhancement campaign in its history as a way to stay in step with its growing customer base’s ever-changing appetites. Many of the chain’s core menu items–including its Chick-fil-A Chick-n-Strips, salads, Cool Wraps, and the Chick-fil-A Chicken Salad Sandwich–received upgrades. The level of success enjoyed by the Chicken Salad Sandwich has surpassed the company’s highest expectations.

“We’ve seen initial sales for this particular product jump 300 percent,” says Vice President of Brand Development Woody Faulk, who has led the menu enhancement campaign for Chick-fil-A.

While the flavor profile of the Chick-fil-A Chicken Salad hasn’t changed since chain founder Truett Cathy developed the recipe more than 60 years ago, the revised recipe is now served on a premium Wheatberry bread with Green Leaf Lettuce and packaged in a clear clamshell, resembling packaging more typical of a high-end deli. The sandwich is available individually at $3.65, or for the first time as a Chick-fil-A Meal for around $6.00.
