As a link off another site I found
www.bariatriceating.com. The woman has a book and there are free recipes listed too. I haven't tried any as I am not eating yet... but a few sounded good enough for me to save them. You may want to try
http://www.obesityhelp.com/forums/recipe too. They have a forum there and you can post different recipes that you like or have tried. If you log into obesityhelp.com and go to the store, there are alot of books there, and a few of them are cookbooks.
I hope this helps!
