Browse food web sites and publications (there is an endless amount of choices out there). Find 2 recipes per week you think you would like. Buy everything you need on Sunday, cook meal 1 on Sunday and meal 2 on Thursday. Mix it up and keep an open mind, and stay away from canned, boxed, frozen and premade items as much as is possible and reasonable, and you'll do just fine.
