What is in the "MEAT" at Taco Bell?

ON the CBS news tonite, they reported that an Alabama Law Firm is suing Taco Bell because it lied about its beefy meat filling. The law firm had the meat tested and it contains less than 35% of Beef meat in it. So what the HELL is the other 65% of ingredients in the meat filling? Oh my gawd, the rumor might be true! It's horse meat!!! hahahahaha Well, I dont care, it sure does taste good! hahahahaha
