I used to meal plan religiously but got out of the habit whilst having house renovated. Trying to get back to it now though.
We also have a sushi night about once a month (usually bought from London on way home, but sometimes homemade by older dc) and I'll often make (once a fortnight) something with wraps, so enchiladas, burritos, fajitas or something similar. If I'm in too much pain to make anything we'll have a takeaway.
On, and I make a lot of traybakes to cut down on prep/watching and washing up. Eg, so last week I got the dc to prepare a load of veg (peppers, onions, mushrooms, courgette, and potatoes) and chop them into similar sized chunks. I then drizzle with flavoured oil and season well with salt, pepper and whatever spices/herbs take our fancy, then I roast until golden and cooked through. Sometimes I'll add a bit of diced chicken or bacon pieces, other times I'll serve it with a baked eggs (cracked over veg and cooked with it for last 10 mins or so).
I sometimes change my mind last minute, or have run out of time to cook what I wanted, or unexpected guests turn up with different tastes, so things do get swapped about, probably at least once a week.
