Eh? The mezes of the eastern med have loads of veg only dishes where the vegetables are treated with love. Northern Africa the same. if you've ever had Italian banqueting food you'll know that many of the courses will be vegetable only dishes. What about the middle East?
I'm not saying these are predominately vegetarian cultures but they are cuisines that have fantastic vegetarian dishes not because of a veg or vegan thing (though sometimes it is) its just because the dish doesn't need meat. Its just that in the UK (and Northern and Eastern Europe in general tbf) veg is so often something that is added to a dish as an afterthought rather than the dish being about the veg. I think more meat eaters would eat more vege dishes if they knew how to make great veg only food, you only have to see the success of the vege street food vendors throughout London.
