I'm going to make your life easier today... I saw an awesome idea on Pinterest for a similar meal plan, but there were only four little boxes. I plan my grocery trips for the whole week, so I've made a printable for us to use to plan out our meals a little easier each week. In the seven boxes, you can put each night's meal. Below you can list the items you need to pick up at the store to make that meal. I normally write in the weekdays or dates in each little box to help keep my mind straight!
You can right click on the image and open it in a new window. All you have to do is print it!
