Not sure if you've thought of this option... Raw Vegan?

I just found this website online, so I'm not familiar with which is the best one -- my husband did more reading up on this subject because he wanted to try it (we have been vegetarian for two years or so and vegan for ten years or so). I enjoyed it, but too much of it upsets my stomach. Still... some of the recipes look yummy, and I would love to add some back into my diet (we've been more vegetarian the past year and want to go more vegan again with our diet). I thought of this because of the heat and energy conservation point you mentioned.

Anyway, try doing some searches for raw vegan recipes. See if there's anything yummy on a site like this: http://goneraw.com/
