Grain-free, keto friendly buns, tortillas and pizza crusts at Mr. Sub


Many Canadians are joining one of the fastest growing diet trends in the world – keto. Just as plant-based meat alternatives have disrupted the meat industry – Unbun Foods has started to replace traditional gluten-free bakery products in the QSR (quick service restaurant) industry.  The company offers a range of grain-free, keto friendly buns, baguettes, tortillas and pizza crusts.

Unbun Foods, Canada’s leader in creating innovative certified keto, paleo, dairy-free, grain-free and gluten-free bakery products, announced the launch of the Keto Bun at MR.SUB locations nationwide.

At Unbun we are obsessed with innovation in order to provide our customers with better-for-you bread alternatives. They never have to compromise quality. Our products not only taste good, but are good for you,” says Gus Klemos, Founder of Unbun Foods, the company behind Keto Buns at all restaurants in Canada and the U.S. “We are proud to be partnering with MR.SUB as innovators in their industry to provide Keto Buns across the country starting today. Now all Canadians have the opportunity to enjoy a MR.SUB sub sandwich without the guilt.”


Aligning with the iconic sandwich restaurant’s menu, including better-for-you Raised Without Antibiotics meats, MR.SUB will be the first sub sandwich chain to offer Keto Buns by Unbun. Joining trailblazing partners in the QSR industry, such as The Burger’s Priest and BurgerIM, to offer certified keto and paleo bun. MR.SUB costumers will be able to swap out a traditional bun on any small sub with the Keto Bun for just $2.29 + tax. The healthy, low-carb alternative contains 6g net carbs, 16g fibre, 16g protein, and only 110-160 calories added.

Since 1968, MR.SUB has been catering to Canadians’ evolving tastes. So we are thrilled to now offer a wide range of menu items that offer new variety as well as address the requirements of those with alternative dietary lifestyles,” says Nicole Johnston, Director of Marketing, MR.SUB. “We tested these items in select locations this spring and the feedback has been very positive. We’re confident Canadians will love the latest additions to the menu.”

About the Gus Klemos

From humble beginnings operating out of a one- bedroom condo selling into three Toronto locations to now over 1,800 locations across North America in only 18 months – Unbun Foods was born from a mission to satisfy founder Gus Klemos’ insatiable craving for a burger without the guilt and empty carbs. Not satisfied with the limited options available, Gus took to his own kitchen to create a product that was healthy and actually tasted good. With the rising popularity of low-carb diets, such as paleo and ketogenic, he identified an opportunity to appease these markets, along with the gluten-free, grain-free, and general health-conscious community.

About Unbun

With Unbun products gaining notoriety in such a short period, the brand’s first major success was an exclusive opportunity with popular burger joint, The Burger’s Priest. The resto offered the first and only publicly announced gluten-free bun option. From then on the growth was rapid, and demand grew cross-borders in 2018 with Unbun expanding to 200 locations across the US in premium burger chain BurgerIM. Starting this October, Unbun will be rolling out its keto friendly pizza crusts nationally.
