My daughters loved The Mary Frances Cookbook. It is a story along with recipes. Might be more of a girl thing, though. You could make him salad chef, or pick a couple things he could help make each week that are in your menu already – measure oatmeal, peel carrots, slice bananas, etc. One of my kids is in charge of toast, another is learning to make the biscuits and pancakes, the oldest granola bars and parmesean chicken. They do these each week to get practice.
