Thanks for the encouragement, and for the cookbook recommendation--I've just ordered one from ABEbooks. I see that there's an updated version coming this spring, too.

I've had one other cookbook recommendation from a friend at work, one that looks to be a different focus. It's "The Calculating Cook: A Gourmet Cookbook for Diabetics" by Jeanne Jones. Out-of-print, but there are lots of used copies out there. The one I ordered hasn't gotten here yet so I can't give you a personal report on it yet.
