all of his books are about cooking simply

How to Cook Everything is a start

but Niq96st is right, get a crock pot. google recipes. all you have to do is chop and prep (which you can do the night before) and put it in the crock pot and you come home to a meal

you can cook nearly everything in a crock pot-soups, stews, spaghetti sauce, desserts, even a whole chicken (which I have never tried)

a rice cooker got you on a quick starch
and veggies are quick to make

bam. dinner.
