According to a report released Monday by the Department of Sides and Garnishes, 85 percent of U.S. cole slaw is never consumed. 'Extensive surveying of restaurant bus tubs and waste bins indicates that for every 120 tons of slaw produced, only 18 tons end up being eaten,' the study reported. The study focused exclusively on U.S. restaurants, as there is no evidence that anyone has ever made cole slaw for home consumption.
