Subway testing meatless Beyond Meatball Marinara sub

Subway has announced it is testing out a meatless sub.

The restaurant chain hopes to attract consumers looking to ditch meat for environmental and health reasons.

The meatball marinara sub will be made with Beyond Meat's plant-based protein.

The sandwich chain will start selling the Beyond Meatball Marinara Sub in September at more than 650 restaurants for a limited time.

Several other restaurants, including Burger King, KFC and Dunkin' Donuts, have also recently started adding plant-based meatless options to their menus.
