This book is excellent. It really does have a wide variety of different things that you can cook...all with a rice cooker. There are a few recipes that require extra steps (things done stove top, for example), but the vast majority are things that you can do with JUST your rice cooker!
Last week, I made an amazing pasta dish with tons of vegetables and so much flavor. I was thoroughly impressed with the meal and it was SO easy to make.
I highly recommend the book to anyone that is short on time, short on space, or has a limited kitchen. Rice cookers and so cheap and efficient and, with this book, you can still have dynamic, tasty, complete meals!
