Carrot dogs must be the most cliché vegan food there is, but it's actually tasty. I like them better made of tofu or seitan, but this is easier and way cheaper. How to do it? Steam the carrot until kind of tender, then fry it a bit using a grill pan for those pretty stripes.
So, the sauerkraut. I'm not sure. It wasn't bad, but not great either.
