Subway® restaurants announced it is the first quick service restaurant brand to offer a one-net-carb bread option for guests, as part of a new product test in partnership with food tech startup Hero Labs, Inc. ("Hero"). With just one gram of net carbohydrates, 0 grams sugar, 12 grams of protein, 26 grams of fiber and only 100 calories in a six-inch sub roll, Hero Bread™ sandwich rolls deliver the signature flavor fans love, with added nutritional benefits.

I’ve always craved more technology in my sub sandwiches. Okay, maybe that’s a lie. I’ve never said those words before in my life. I do enjoy a toasted Subway sandwich, and it looks like that next sub is about to get more tech-filled with the addition of Hero Bread sandwich rolls, and Tom Brady.

Subway is all about options, from its sandwich toppings to the bread they go on. The sandwich purveyor already offers more than three types of bread, and it's adding yet another—this time for more carbohydrate-conscious consumers.

After the rollout of the biggest menu revamp in brand history this summer, you might think Subway is likely done with menu innovations for a while. But it turns out, the chain continues to build on the Eat Fresh Refresh campaign and has just come out with a new bread that's unique across the fast-food industry.

Imagine a bread roll much like Subway’s Italian white bread: soft, fluffy, carbohydrate-dense. Now imagine if that bread had zero grams of sugar, 12 grams of protein, and only 1 net carbohydrate per serving.

That’s the product that California-based startup Hero Bread recently launched in Subway sandwich restaurants.

SAN FRANCISCO — In the eyes of Ray Lane, managing partner at GreatPoint Ventures, San Francisco-based Hero Labs could do for baked goods what Beyond Meat did for plant-based meat: change the game. With real synergy between the two brands, Hero buns and tortillas started appearing in the Beyond Meat board room.

Hero Bread is introducing its sugar-free, 100 calorie, low carb bread to more than 1,600 Subway franchises nationwide after a successful initial rollout to select Subway franchises in October 2021, according to the company. The bread is now available in seven new markets, including New York City; the Bay Area; San Diego; Portland and Medford, Ore.; Portland, Maine; and Salt Lake City.

Lil Baby, Tom Brady, Kevin Durant and The Weeknd are some of the celebrity investors in Hero Bread, a San Francisco-based food technology company founded by 32-year-old former Tulsan and Holland Hall grad Cole Glass.

Carb-conscious fast-casual diners have something to celebrate this week, as the nation's largest sandwich chain is poised to serve subs on low-carbohydrate bread that, according to some, doesn't compromise on flavor. In a press release, food tech company Hero announced that its sandwich rolls, which contain just 1 net carb and 0 grams of sugar per 6-inch serving, will soon be available at select Subway locations through mid-December. Hero and Subway partnered to introduce Hero Bread, the first bread in the quick-service industry to have such a low carb count — as well as 12 grams of protein, 26 grams of fiber, and 100 calories — per serving.
