I'm one of those crazy people who do "everything" on the computer.
I found this nifty Microsoft Excel template for a weekly Meal Plan. It helps me a ton when I'm making my grocery list out to have a meal plan to refer to.
It's an extremely simple template, but it saved me the time of making one myself. It's at Microsoft's Office website. office(dot)microsoft(dot)com/templates
Look under Healthcare and Wellness, then under Diet and Excercise. It's called "Weekly meal planner"
