Taco Bell (YUM -2.2%) says it will defend its reputation against a lawsuit that alleges its beef isn't so beefy. The fast-food firm says its beef is "100% USDA inspected" and its meat mix is "88% beef and 12% secret recipe," but the lawsuit claims the mix is about one-third beef and two-thirds "isolated oat product" and other additives.
