NEW YORK (February 13, 2013)—The Taco Bell chain will launch its Doritos Locos Tacos in Cool Ranch flavor on March 7.
The rollout comes a year after the Doritos Locos Tacos were launched in a Nacho Cheese flavor.
Taco Bell said it already sold more than 350 million of finger-staining tacos, making them the chain's biggest-ever product launch.
CEO Greg Creed told the Associated Press that Doritos Locos Tacos now account for about a quarter of the chain's taco sales.
Creed said he plans to keep introducing new Doritos flavors as well.
The tacos have helped Taco Bell stage a comeback after a lawsuit in 2011 alleging its beef shouldn't be labeled as such because of its other ingredients.
The suit was later dropped.
