Beyond Meat, El Segundo, Calif., announced a culinary partnership with Subway, Milford, Conn., to test exclusive plant-based protein options. Starting this September and for a limited time only, Subway restaurants will test the Beyond Meatball Marinara sub in 685 participating restaurants in Canada and the United States.

The strategic collaboration reflects Subway’s continued culinary innovation journey to offer more best-in-class food experiences.

The Beyond Meatball Marinara sub is drenched in marinara sauce, Provolone cheese, sprinkled with grated parmesan cheese, perfectly toasted and features the Beyond Meatball created just for Subway. The sub delivers 24 grams of protein per 6-inch sub.

“Subway appeals to so many fans because we truly offer something for everyone. Our guests want to feel good about what they eat, and they also want to indulge in new flavors. With our new plant-based Beyond Meatball Marinara sub, we are giving them the best of both worlds. And, we are particularly excited about debuting a co-developed product that can’t be found anywhere else—the Beyond Meatball made just for Subway,” says Len Van Popering, chief brand and innovation officer for Subway.

“We’re excited to partner with Subway, and are grateful that the menu team through to senior management has entrusted us as their innovation partner to deliver delicious plant-based proteins to their guests. We look forward to a long-term partnership with Subway, as we together, serve and delight existing and new fans of this iconic chain,” says Ethan Brown, founder and CEO of Beyond Meat.
