Another one I've remembered.
For years, we did a Sunday roast dinner. When
I was mooching about cooking it, I would also do a double batch of something for Mondays dinner, so I only had to reheat a sauce when cooking pasta/rice/boiling already peeled potatoes etc. Or turn off the oven set on a timer.
Things like spaghetti Bol, chilli, curries, stews, lasagna, shepherd's pie, chicken and mushroom pie, smoked fish and broccoli pie etc.
The second batch was frozen to enjoy another day next week (and I had a previous week's frozen offering for a different busy midweek night his week).
So that was 2 nights a week where I had minimal cooking at the point of arriving in, emptying school bags, hearing the news of the day etc, for the sake of a little extra work when I was already in the kitchen anyway.
It was nice pottering time anyway for me as we tend to wash and dry laundry as the week goes on to keep control on the mountain, but all clean clothes go into a hamper (which can be invaded if urgent clean clothes are needed) to fold in front of a movie at the weekend (usually together). And DH does all the household ironing watching country file on Sundays while I cook.
