I have been vegan for about twenty years. Before that I was a vegetarian except starting when I was in college when I became a meat and potatoes guy for about ten years. Youthful experimentation, you know.
It is now very easy being vegan. I know I need to plan but veggie food seems to be available.
Once upon a time I would eat anything vegan. Now I am more selective. I avoid salt and refined sugar. I don't purchase frozen foods with an ingredient list that indicates it came out of labratory.
Looking for vegan restaurants enriches my travel experience. In cities like Paris I dine in residential neighborhoods for half the price of the better known areas. I enjoy some local flavour I would not otherwise be exposed to.
I do lots of research online before I travel. I use "happy cow" to find veggie restaurants. Sometimes I just stumble opon a find. I like that, too.
