Firehouse Subs, a Restaurant Brands International (RBI) brand, has announced the re-launch of the Pepperoni Pizza Meatball Sub at all its participating locations in the US.

The Pepperoni Pizza Meatball Sub was first launched in 2021. It features Italian meatballs, marinara, extra provolone, crispy pepperoni and Italian seasoning on a toasted garlic bread roll.

Firehouse Subs chief marketing officer Yosef Hojchman said: "The classic Firehouse Meatball sub is popular among many guests, but when you combine three Italian American staples – a classic meatball sub, pepperoni pizza and garlic bread – you get a delicious, indulgent sub that wows the taste buds.

"Guests have been asking for it and we're excited to bring it back."

The restaurant brand stated that its new sub is available for a limited time period and customers can place their order through the app or online.

It added that Firehouse Subs Rewards Members can get a medium Pepperoni Pizza Meatball Sub for just $6 when they purchase through the new the company's app.

Last month, RBI announced the opening of its first outlet in Zurich, Switzerland.

The launch was part of its global expansion strategy, which includes its development agreement to launch the Firehouse Subs brand in Mexico.

The company's Zurich location will have the capacity to accommodate 62 guests and features self-order kiosks, mobile ordering and a dedicated click-and-collect area.
