I have always thought the meat was actually created from worm protein..you know that MickeyD's owns the largest worm growing facilities in the world,right?
I heard that McDonalds actually uses ground up mealworms in their hamburgers because mealworms have tons of protein and the easiest and cheapest to buy.
I hate to bring this up, (a terrible pun, given the subject matter)but on any given day in North America, there are approximately twenty five thousand missing people, and a similar number of missing pets, dogs, cats, canarys, etc. Where do they get all the meat for their burgers?
