this was yrs ago..(more than twenty)but i worked at restaurant in Parkersburg,wv
we ran out of burger so we had to call around and the restraunts just traded things if they ran out and we called to borrow some meat and they didnt have it like meat it was dried?you had to add water to it for it to puff up?
they may have changed it by now...
i dont know i dont eat it because it makes me sick everytime...stomach cramps etc.
