Can you recommend any particular book? I gather that the olive oil is a key here, keeps you from getting too hungry, and probably provides needed fat.
Unfortunately I can't really name a specific cookbook. I don't really use cookbooks. However, I have seen a few on Amazon.com when I got curious. I recall there seemed to be a couple that seemed very popular.
Yes, I use olive oil, feta cheese, or parmesean in almost everything.
