I know you're joking, but in all seriousness, at least in the Netherlands it would be very difficult to be vegan, and VERY expensive. Just an example, I have lived here for 16 years now, and last year was the ONLY time I have ever found a spaghetti squash, and only one time. Our grocery stores have the basics; broccoli, carrots, lettuce, green beans, etc....but the produce section is about a 5th the size of the produce section at an American grocery store. So if you were looking for anything but the basics, good luck. Even the weekly open air markets where farmers sell their wares don't have anything other than the basics. There is no cheese substitute that I know about....there are a few milks like almond milk, and soy, but your diet wouldn't be particularly varied. You'd have to eat pretty much the same thing every day. We just don't have the options here for meat subtitutes, dairy substitutes...I can't even buy corn flour at my grocery store much less specialty diet items. You'd have to go to very specialized stores and spend beaucoup bucks to manage a vegan diet here, I'd think.
