With the British media's preoccupation with where food comes from, I've seen stuff like this before and always wondered why they can't artificially flavor other, healthy but still cheap material.

I'd eat a burger/nugget made of mushed up, chemically enhanced cabbage/potato/soya/whatever, as long as it tasted as "good" as the existing thing. Why isn't this more common than mushing up animals? I'd have expected it to be cheaper and people are easily fooled by artificial flavorings, but they'd be slightly more healthy and slightly less gross into the bargain.
