This week, Mexican-inspired chain Taco Bell debuted vegan Diablo Tortilla Chips at select 7-Eleven locations nationwide. The new chip flavor (boldly spiced with hot peppers and lime, and colored with vegetable juice to achieve its black hue) is an extension of Taco Bell’s three-flavor vegan chip line—Classic, Mild, and Fire—inspired by its popular hot-sauce packets. “Our iconic sauce packets were our original inspiration for how to give fans a new way to access a taste of Taco Bell at retail,” Taco Bell Chief Global Brand Officer Marisa Thalberg said. “The new Diablo Tortilla Chips build from that inspiration, letting us serve up our hottest chip yet that’s completely unique to Taco Bell, from its dark and smoky packaging with saucy wisdoms, to the flavor of the chip itself.” The limited-edition chips are available at select 7-Eleven stores until October 31 and will expand to other retailers throughout November. As of September, competing chain Del Taco began serving a vegan meat option, thanks to its partnership with Beyond Meat, that can be ordered in menu items such as tacos, burritos, and nachos at two Los Angeles locations with plans to expand the offering nationwide.
