Aw thanks ORChick--and everyone else who has commented so kindly
My plan is based a lot on what we have on hand in the pantry and freezer and is pretty much what we usually do. So I have the benefit of having done this before--just not in this format. I've usually just written it all out on a paper calendar in the past. I like the Word document better, because I can save it from month to month and "recycle" plans I've used before. The paper calendars get pretty mucked up by the end of the month (I just print out calendar pages) so I haven't really saved any of them. Now if a page gets mucked up, I can just print a new copy!
Yup, stuff like potluck at church etc. can mess the plan all up, and I often freezer-cook so I usually have a few casseroles put by for instances like that, but I really find that when I calendar it all out like this it really keeps us from eating out or buying impulse groceries. If we skip a meal/day we just pick up where we were.
I should also explain that each person in my family chooses what they want for breakfast every day--we don't all eat the same thing, except on weekends. Each kid as well as my hubs pack their own lunch after breakfast, as per the meal/snack plan. I work at home, so I eat mine when I get breaks.
Dinner is sit-down together every night, even nights when the girls have Girl Guides, music lessons, or Youth Group activities--we only get about 20 minutes for dinner on those nights between when hubs gets home and we need to drive a kid somewhere, but I've got the timing down just right at this point and we just do it and then get the dishes cleared and into the dishwasher before we leave.
(We only run the dishwasher once a day, after dinner, and pots and pans are washed as they are used/emptied onto serving plates unless we serve out of a cooking dish like a casserole or pyrex dish).
I filled it with delicious Shepherd's Pie
