I like both Kathleen Daeleman's books for great recipes made with ingredients that are easy to find and often in your pantry. She has two: Getting Thin and Loving Life (blue) and Cooking Thin (yellow). I think both are available on the used market. The Cooking Thin one is available in paperback. She'll make you laugh while she's at it.
I also have a lot of good luck with Cooking Light stuff. I don't own any cookbooks but they are out there and the magazine is great.
