Beans, rice, chicken...all this sounds cool, BUT...as far as I know, in USA, fast food restaurants like to put SUGAR in everything they can, even SALADS. I'd vomit if I tasted sugar in salad.
PS: We do have McDonalds here in Slovenia, but I don't eat there. No f'ing way.
PS #2: Have anyone tried horseburger yet? It's yummy.
