Simplifying Meals: Master Menu Plan

I've become pretty lax this summer with menu planning, cooking and grocery shopping. As I look to the fall and the demands on our time, I want to make the most of my time in the kitchen and at the grocery store. So, I need a plan that will be a guide with lots of room for flexibility.

We'll see how it goes, but here's what I'm thinking. There will always be a fruit and/or vegetable offered with each meal, and sometimes bread.
