About 5 percent of sales at Caprotti's comes from catering, but the chain expects its new expanded catering menu to double that number.

Capriotti's has had catering since it opened in 1976 but it expanded the menu this year, adding the meatball subs bar.

Doug Reifschneider, Firehouse Subs VP of marketing services, chatted with fastcasual.com about how more consumers these days are demanding catering options from fast casuals.

Nationwide, 4 percent of Firehouse sales come from catering, although many franchisees sell 10 percent or more of their annual sales in catering, Reifschneider said.
