Thanks, lmerullo,
1) You're right--I think he meant keeping all the fiber in it, but I'm not 100%sure
2) He avoids fat, meat and dairy because his new digestive tract: embattled with chemo and radiation, and cut up to be half the size it was, cannot tolerate them--as he said, if he has a pizza, or a filet mignon, he very swiftly vomits or it comes out the other end. Yet, I still think his self-defined nutritional protocol his helped him. And it's not that he doesn't eat any animal-based protein--but he restricts it to chicken (organic) and fish.
I think you guys have already talked me out of adding yet another culinary trinket to my collection. For me, it would be about convenience. It gets boring chopping vegetables.
