That sounds like a great idea, I hope you do it! I'm pseudo-vegetarian and also live in France and yes it is difficult to find restaurants or chefs who specialise in vegetarian cuisine. So there's a niche here waiting for you. There are a couple of names you could look up, such as Marc Veyrat who runs a great restaurant in Annecy in Haute-Savoir called La Maison de Marc Veyrat, and he specialises in plant based cuisine. Another is Michel Bras from Laguiole in Auvergne, his restaurant is called Bras : ) You could do a normal cooking course then specialise with one of these chefs for example. Try googling them to look at their websites. My husband is a chef but not vegetarian, so I've been working up my own recipes and publishing them on the net. Please feel free to have a look at tell me what you think, there is a comment box at the end of each. The links are below and the articles include photos. Hope you like them. Best wishes and good luck.
