"Restructured Meat" ~ includes the McRib, chicken nuggets, meat the U.S. military buys. . .

I had never heard of restructured meat.  While it sounds gross, it is just a meat technology.  It's a process where salt is used to extract proteins from the muscle.  The proteins become an emulsifier that holds all the little pieces of meat together in whatever shape is desired.
