You should see how shelf stable canned chili and cheap beef stew is made, it's vomit inducing. I still eat it because whatever man.
Well, aren't most nuggies made from mechanically separated chicken - the pink goop you get by grinding up bones which still have small amounts of meat on them after more recognizable pieces of meat like breasts and thighs have been removed and then mashing the mixture through a sieve to filter out the bone chunks? If Chick-fil-a's nuggies are made from actual hunks of chicken, that is somewhat remarkable.
Me, I've never had Chick-fil-a's nuggies. I just eat their sandwiches because I am a fucking adult.
