If you need simple, tasty food that your kids will actually eat may I suggest 100 Recipes from America's Test Kitchen? I've looked at books like this before, and have been disappointed by lists of crazy ingredients or fancy twists on basic food. This book isn't like that. It contains basic recipes that use the best ingredients cooked in the best way.
A real sign of how basic these ingredients are: I was reading this book in the car on the way home from a hike, and saw a recipe for Pan-Seared Chicken Breasts. I decided it looked good, and was able to cook it from things I had on hand. That never happens to me due to the small children who live in my house and eat through all available ingredients as if they were a swarm of locusts.
I've never been tempted to cook through a cookbook before, but this book might just get me to do it. It seems as if it can get me to rise above the daily beat down caused by my lack of time combined with my suspicious of anything that is not pasta kids - at least once or twice a week.
I got this book from the library, but I'm planning on buying my own copy using cash money from the bookstore. That's saying something.
If you too are beaten down by life, here are some more cookbooks that might bring you back from the dark side:
