Chipotle Mexican Grill Inc.'s plan to turn a traditional Mexican dessert into a growth driver has sputtered, leaving the beleaguered burrito chain seeking other new menu items. The dessert known as bunuelos, a fried-tortilla dish topped with honey, sugar and cinnamon, wasn't a hit. The item is "on hold" for now, according to spokesman Chris Arnold. The company has struggled to reignite growth after an E. coli crisis torpedoed sales in 2015.
