Firehouse downsized all the subs on its menu, with the mini sandwiches coming in at under 500 calories and starting at $3.99 in price. The move is a strategy to boost traffic from 2-5 p.m., capitalizing on a time when hungry guests may be seeking a snack. Overall, 80% of consumers say they snack between meals at least once a day, and 57% say they snack twice a day or more, according to Technomic’s Snacking Occasion Consumer Trend Report.

To make the snackable subs, staffers simply cut the sub roll in half and fill it with smaller amounts of the same ingredients available in Firehouse’s signature sandwiches—very little labor and no extra SKUs required.
