This is mechanically separated chicken.
It’s what all fast-food chicken is made from—things like chicken nuggets and patties. Also, the processed frozen chicken in the stores is made from it.Yes, this is coming from a guy who enjoys sweetbreads, lengua and head cheese. And it turns out that things aren't quite as nasty as dire as the picture painted above. But still.
Basically, the entire chicken is smashed and pressed through a sieve—bones, eyes, guts, and all. it comes out looking like this.
There’s more: because it’s crawling with bacteria, it will be washed with ammonia, soaked in it, actually. Then, because it tastes gross, it will be reflavored artificially. Then, because it is weirdly pink, it will be dyed with artificial color.
