Accidentally Vegan is it's own subgenre of Vegan Food. I have made most of the four dollar sign stuff myself from scratch professionally and can tell you how the switch sausage is made. It's made without that much effort, this shit is super fucking easy to do at home. I've worked in a few Vegan restaurants (wish I could still do so but I get paid more and have clout where I am) and have had time to mess around with some weird ideas. Fundamentally though what people like about meat isn't the taste of meat, have a meat eater chomp down a boiled chicken or whatever without seasoning and see how much they like it. People like the bullshit that is done to meat before they eat it, that's the star of the show, the rest is flavor sponge. So many things can be flavor sponge.
