This season’s lineup includes a new chicken sandwich, the return of a fan-favorite beverage with a sparkling twist and two new waffle potato chip varieties.

Guests will be able to receive a free Chick-fil-A chicken sandwich, spicy chicken sandwich or grilled chicken sandwich starting now until Saturday, the fast-food chain said in a news release last week. To obtain the free sandwich, guests must place a mobile order or open the app in-restaurant.
