Vegetarianism has been a culinary philosophy for thousands of years, but not so much in the West, until it started to make a comeback in the early Twentieth century. It was taken on board by the Hippy Movement in the Sixties and Seventies, because any of them drew inspiration from the East and in particular Buddhism. The children of those hippies often continued the lifestyle imbued in them by their parents, and have now passed it on to their own children. Nowadays, very few towns, no matter how small, are without a vegetarian restaurant.
This is not a recipe book, although it does discuss vegetarian food and does give a few example recipes. It is really for those who want to know more about vegetarianism, perhaps in order to better understand the movement or their vegetarian friends and family members.
I hope that you will find the information helpful, useful and profitable.
