I'm also constantly amazed, and this is not KFC specific, that we have to make plant based food look or taste like a specific meat product to get most people to embrace them, when they are perfectly valid as their own items without a fake meat name / colour / shape / marketing.
I thought the same when I first heard about vegan meat alternatives, way before Beyond Meat and similar even became a thing. "Why would a vegan even want to eat something that's called a 'schnitzel'?", or "If they are interested in something that looks, smells and tastes like a sausage, why not be honest with themselves and just buy the real deal?".
Now, it seems obvious to me that these types of meat alternatives aren't offered for those considering themselves "vegan", but rather for us conscious meat eaters. I don't mind eating vegetarian or at least a very reduced amount of meat most of the time - but every once in a while, I do crave for a medium-rare steak, or a juicy cheeseburger, or the admittedly unhealthy stuff that KFC et al. have to offer.
If I can have the tastiness of that without the moral dilemma, all the better - but in the end, a bowl of salad just isn't the same. ;)
