I've read her book and have her DVD (it's very helpful).
I am not a raw fooder, but I do believe that a high -raw diet (80% raw) is very beneficial, and I try to start each meal with a raw food.
One thing about Cohen's stuff: she's really heavily into using the dehydrator. I've tried several recipes, and most of them are good. The stuffed corn tortillas are yummy, except I didn't get the 'crust' dry enough and so it ended up a bit gummy. The collard rolls are tasty (though I've tried another version of them, and not the exact one that Cohen uses).
