Hm, maybe. I mean I like to cook quite a bit so I'm not really the best to ask if it's easier, but there's also vegetarian junk food. Pizzas, fries, falafel, etc. As for expensive, I think here it ends up being quite a bit cheaper. Fast food isn't cheap the same way it is in the states (a mcd's menu will set you back ~8 euro, I can cook for around 2 euro a person) so that might be a contributing factor. For example (thai) curries are ridiculously easy to make and still be cheap & tasty, you just throw in some vegetables, coconut milk, spices & curry paste, something protein-y and you're set. In my case it mostly required a different way of looking at food, and I've heard this from a few people who became vegetarian after they learned cooking with mostly meat -- instead of thinking "i'd like chicken with..." or "beef with" you have a different starting point. Not hard to change, just different.
