^^Just to clarify, mollycakes, the "gourmet" raw stuff that Penny is talking about is the raw cakes, breads, burgers, all that sort of stuff. The only tool you really need to be raw is a knife to cut your fruits and veggies - and even that you could get by without if you just used your fingers to peel fruits and ate your veggies whole.
You could also make salads, raw soups (blender), that sort of thing. So raw can be done really quickly if you want - Cut some veggies and lettuce, stick it in a bowl, mash some avocado on it, squeeze a lemon, boom, salad, done.
Grab a few bananas, peel, eat, done. Or, it could be much more complicated. Soak raw nuts, puree with dates, form into cookies, dehydrate overnight.
As for grains, some can be sprouted and eaten that way, and many raw foodists do that. But you'll also find people who simply don't eat them. Fruits, veggies, nuts, seeds, voila.
