I thought I would share some of my tips for menu planning:
Pick a day where doing a full grocery store trip works for you. For us, that is usually Sunday, but if your time is more flexible, there are certain days at the grocery stores when the food is fully stocked, when things are marked down, or when it is less busy. Find out what works for you.
On the day before or the morning of that day, make a menu for everyday of the week. Look at your calendar and plan around nights when you (or all of you) are out of the house and when leftovers are needed for lunches.
When Dave and I will be home alone at suppertime, I like to make something the night before that we can just reheat, or pick something that Dave can make before he goes to pick up E. That way we are less busy getting supper ready while trying to entertain E.
Cook big pots of things to reheat or freeze.
Using up leftover turkey and orzo pasta
Write down your menu, preferably on a chalkboard so that everyone in the family knows what you're having.
Make a complete grocery list from the recipes, and then go through your fridge and cupboard to check off what you already have. Even though I'm in the kitchen when making the list, I sometimes forget to add items to my list thinking I already have them, so if you just add everything, then you can go through and check before you shop.
Avoid cooking what is just lying around in your cupboards
