I also look forward to the cookbook, but you really don't need one to enjoy this way of living.
I take a look at a recipe and see how I can make it healthier and taste better. Substitute butter and margarines with oils, use whole grains instead of white, add in more veggies than the recipe calls for, cut back on sugar.. etc. Just arm yourself with your list of Wave specific foods and experiment! That is the fun in this way of eating.
At the top of the forum are several Sonoma friendly recipes. I am trying to post as many as I can as I create them. I have lots more, but not enough finger strength or time to type them all.
