"I've never seen the reason for 'dressing it up' to resemble the meat version"

Pretty simple. Most vegetarians are vegetarian for ethical reasons, yet many still enjoy junk food and the taste of meat, same as everyone else. Fake meats may not be great, but to the vegetarian who still hankers after meat, it's straight a substitute.

I personally *do* eat meat (including game, free-range fowl, and fish), but I don't eat processed shit meat, so if I fancy 'junk food' I sometimes buy vegetarian substitutes myself. Tivall frankfurters are my favourite.

Likewise, I for one have never seen the point of meat flavoured crisps, prefering straight potato flavour, but some people like 'em. I've also never seen the point in much highly processed and frozen (food be it meat-'based' or otherwise), but there's a massive market out there for it all, so I guess someone must be digging it!
