The stuff i've seen is huge precooked bags of grey grade F meat that was boiled in a huge vat of water to reheat it.

Okay, well, then it's changed since I worked there years ago. Because when I worked there, we cooked the stuff ourselves. It was not precooked, and it was not boiled. We cooked it and seasoned it ourselves. And the grade of meat wasn't bad.

Heck, we even cooked the refried beans ourselves from actual real beans. Had a big old pressure cooker over a gas flame. Kind of interesting, really.

I'll see if i can pick up another copy of that book this weekend and lend it to ya

Probably best not to. I'm definitely in the "ignorance is bliss" camp. What's the old saying? If you wish to retain your respect for Politicians and Sausages, best not look to closely at how either is made.
