It's so odd to me as a veggie that people want something that "tastes like meat". If you've been immersed in decent veggie food for a while this isn't something you crave. Why would I want to eat a bit of dead animal? It's something I might do in a survival situation in a barren place, like Han Solo or something, but not if there are fresh veggies to hand.
If you want to do this for ethical reasons, which you should, then just eat vegetables. They taste way better. You just have to recalibrate your senses to deal with the higher levels of flavour.
But if people really want "chicken nuggets" for some reason then there's no reason it should have to involve animals at all, so this is a good thing, I guess.
