I'm curious - how common are vegetarian and vegan options in the US? Is it hard to find these options in supermarkets, or when dining out?
I've never been to a UK restaurant without a decent selection of veggie options, and vegan ones are becoming more common. Food is also pretty clearly labelled in the supermarket and there's plenty of variety.
As I understand it, vegetarian means that one doesn't eat meat, and some veggies eat fish whereas others don't. Vegans abstain from all animal products, including things such as milk and eggs, and if they're true vegans they try and avoid using things like leather too.
