I've got "The River Cottage Family Cookbook." It's got some great recipies in it, ranging from the ridiculously simple, up to more complicated stuff, all of which are down-to-earth practical foods (in fact, I recently posted a question about some cookies I made following his recipie.)
As a bonus, it's written in a way that's easy to follow, and geared around getting kids involved in helping the parents. There's plenty of pictures too, so you can see what your food should look like.
