I bought it, probably 7-8 years ago, then got rid of it. I think it depends a lot on how you cook/eat. At the time of ordering, I was trying to cook from scratch and eat inexpensively, which I still do, but it had a lot of stuff made from white flour, lower in protein, etc... . That's not to say all the recipes, though.
Fast forward to a few months ago, and I was (still am) on the facebook page for it so it was on my mind. One day at my volunteer job, I spotted a copy of it on a book cart and asked the librarian about it. It was donated to the library and she was just looking at it before putting it in the yearly book sale books. She said I could take it home for awhile. I think it was a slightly different edition than I had owned, and I did cook one recipe out of it, the Cheeseburger Rolls (or something like that). But it was a bread recipe with a small amount of protein, and ultimately, I didn't purchase another copy after looking at it and returning it to the library.
