We’ve all heard a joke, I’m sure, similar to such at one point in our lives:
Jon: …ah, here’s a (McDonald’s) burger left over. Want it, Jack?
Jack: Nah, I’m full. Care for it, Lisa?
Lisa: No thanks, I’m vegetarian.
Sue: Don’t worry; it’s not meat, it’s McDonalds…
and, a laugh was had by all.
It seems, however, that McDonald’s does use 100% pure beef in their patties. Therefore, I’m wondering if there are any fast food chains that indeed use something like soy protein to stretch the beef, all the while making no steadfast claims about their “hamburgers made with beef”?
