In a month when just about everyone seems to be hitting the gym and focusing on clean eating, California Tortilla has rolled out a “Super Food Burrito” stuffed with all the right buzzwords: kale, avocado, quinoa, whole wheat and “GMO-free.” The $7.39 dish is currently slated for a limited run, but a strong early response suggests it may end up sticking around. “We wanted to come out with something especially healthy during this first quarter when so many people are starting their diets,” says Keith Goldman, chief operating officer and head chef for the Rockville-based restaurant chain. “It took us a while to figure out how to make kale taste good,” he chuckles. “But if the first few days are any indication, this burrito is going to be one of our top sellers.”
