the way they used to make mcnuggets:
they would take all the leftover chicken parts, put them in a large bowl with holes in the side, then spin it really fast (think washing machine on spin cycle) until any meat left would exit the holes and only bones/cartilage would stay in the bowl. The meat is collected and sqirted into molds to form a shape, then fried.
i dunno how they're made now.
