I meal plan but i dont allocate days for meals if that makes sense. Like i'll have a list of 8 or so meals for the week, buy the ingredients for them, then cross them off as we eat them.
That is how I am making it work for us. I make sure I have a mix of meals that can be cooked quickly or that need the arvo in the oven. I try to match them to the day that suits, but sometimes plans change, so I need to switch around.
