I wanted our food prep to be simplified this year anyways, so over the holidays I worked on modifying our system a bit. We now only plan for 3 meals a week and the categories are pared down.
I disassembled our enormous recipe binder and pulled out our weeknight standbys and then separated them into the four categories I'd selected (the extra category is for sides, in case we feel like adding them to a meal). The remaining recipes are in a new binder which is more for special occasions or entertaining. Each week we plan for one large salad (something that will hold up in the fridge and make good leftovers), one hearty meal based on lentils/meat/pasta (split into three sections for ease) and one quick meal. I made a list of our usual quick meals and the ingredients we'd need for them, along with basic instructions. I don't use a recipe when I make a frittata, for instance, but that sucks for D, who would prefer to work with instructions. This way we have everything pulled together.
To set up meals for the week we do a quick scan to see if we have partially used ingredients from the week before. Then we just choose one recipe from each category, make the grocery list and we're good to go. Having the sections split up this way makes it much easier.
