I am neither a professional chef, nor someone with a lot of time to cook--but I do like to make tasty things that don't take too long. This book is divided into two sections, what Orr calls "Regime" cooking -- in other words, everyday dishes that can be prepared quickly and simply, and the more exotic dishes (though not terribly complicated) for entertaining. The Regime part is simply great. He uses a few spice blends that you can either mix by yourself or buy from his website at a very reasonable price (I'm about to buy them--for the amount I cook, it's easier, and they seem really delicious). He uses low fat, low sodium recipes, but full of flavor...and the stuff is just great. For instance, who knew that by adding a little orange zest into oatmeal you could elevate the taste? I got this book as a gift about three years ago, and it was sitting on the shelf until I pulled it down a few weeks ago. There's something joyful about Orr's approach, and it actually feels life changing. I am enjoying these recipes enormously, and thinking differently about cooking. One other commenter here noted that you can use the recipes exactly "as is," and that is very true -- but if you're missing some ingredients and have just a little facility in the kitchen, you can improvise and swap out other ingredients pretty easily. In fact Orr often suggests alternative ingredients or spices. Anyway, I am in love with this book.
