Meal Planner. Except I like the chalkboard idea on the inside of the pantry. So just put this design on the chalkboard. Could also make the door magnetic so you could put the shopping list on a paper so you can just grab it and go
Some great ideas for a household binder: school flyers, contact info for doctor's dentists, insurance policy numbers, could add list of recent appointments and outcomes, a baseball card sleeve for repairmen business cards, a home cleaning checklist in laminate, home maintenance for air filters etc, auto maintenance, a place for cards for birthdays and a birthday list, coupons for eating out.
