I don't know how you split the chores up in your family, but one of mine, is doing the weekly grocery shop. There I was thinking chores would end when I left home! My recent addition to the family has taught me that is definitely not the case! Anyway, I had a cool tip that makes this simple, and saves both time and money - a smart little app and some helpful preparation (from my wife - its a team game after all).
My wife maintains a rotating menu planner that we try to stick to as much as we can. There is a reasonable amount of variety in this, but not so much that it makes things complicated. I think we have a plan for about a fortnight, and then we start repeating. There are a few weekly duplicates. I am not much of a cook, so when I take my turn in the kitchen, it tends to be spaghetti bolognaise and pizza! Alan Henry has more cool tips on creating menu plans that is worth looking at.
