I don’t follow. As a meatatarian I eat a lot of chicken, among lots of other tasty, meaty critters, but I’ve also had a lot of vegetarian meat analogues and I can honestly tell you, when heavily breaded and drowned in sauce a la sweet and sour “chicken,” even I can barely tell the difference without dissecting a piece. I am continually surprised at how well they can make high-quality TVP imitate chicken (other meats not so much, but they’ve got chicken down).
My GF has been a veggie over 3/4 of her life, a good 26 years or so. For all intents and purposes at this point, that’s essentially her entire life, at least regarding this particular aspect of it.
