Vegetarian hot-dogs are pretty much indistinguishable from the meat ones.

I also occasionally put fake bacon pieces onto an okonomiyaki.

Neither substitutes hold a candle to quality meat, but I can detect little difference between them and the cheap pork products that make up the bulk of what supermarkets in England sell. It grieves me that pigs are bred and killed to make the sort of garbage these fake tastes are an adequate substitution for.
