It's time to become a vegetarian. An Alabama law firm is filing a class action lawsuit against Taco Bell after discovering that the “meat” used in their dishes isn't really meat at all, at least not according to the USDA. The "taco meat filling" as it's written on their containers has only 36 percent real beef; the rest is a combination of chemicals and odd-ball ingredients like 'cocoa powder'. The USDA defines "meat taco filling" as having at least 40 percent fresh meat. Taco Bell spokesman Rob Poetsch issued a statement that read, "Taco Bell prides itself on serving high quality Mexican inspired food with great value. We're happy that the millions of customers we serve every week agree. We deny our advertising is misleading in any way and we intend to vigorously defend the suit."
