What's a good bible on vegetarian cooking? Some years ago I decided to eat less meat and to successively becoming a vegetarian. I haven't learnt any particular dishes though, mostly just improvising with veggies/beans/nuts/cheese as staples – and that's fine, but I would now like to have some new inspiration from a good vegetarian cookbook (meaning less animal products is preferred, but dairy products and eggs is ok).

To make this question possible to answer, this is what I'm looking for:


A sort of a vegetarian's bible. Doesn't have to be very new, I'm thinking bible like Julia Childs' Mastering the Art of French Cooking. Should be very comprehensive.
Should have some dishes that are quick to make and some that are slow cooking.
The dishes should be something you can eat on a regular weekday. Some special ingredients can be hard to find or be a bit expensive, but the staples should be quite cheap and easy to get (I live in Sweden, but have Asian and Middle Eastern food stores nearby).
The recipes should try to follow the (Swedish/European) season if possible.
The cookbook can very well be of Indian cuisine (I hear they like their vegetarian dishes), so some ingredients have to be imported in that case of course.
Language: English or Swedish.
I'd recommend Mark Bittman's "How to Cook Everything Vegetarian", I use it all the time. It's certainly what I would call comprehensive; besides containing tons of recipes for everything from entrees to breads to soups, the sections are prefaced with tips on how to improvise or switch up the recipes as desired, including vegan alternatives.
