Live alone. Meals are a variety of pasta, curries, salads, soups, pho and things cooked under the grill or in oven - fishcake, sausages, pies etc.
Not mentioned lunch situation- unsure if wfh, work away from home. On days of working- carry on as per normal. If got a day off and usually have it with your wife - beans on toast, sandwiches, bacon butty etc.
If your wife doesn’t like a certain food or cuisine and you love it - use this opportunity to have it at home!
slow cookers a win for me.
diced potatoes+Carrots + 4 shepherds pie sachets in slow cooker.
fry onions/garlic add them to slow cooker.
Wait 6 hours.
fry qourn mince on it's own then layer into foil containers. (I hate beef mince and qourn should always be added at the end or it will lose it's texture)
add a tin of marrowfat peas to slowcooker and leave to cool. (empty the liquid from the can, fill it with water and shake, repeat 1-2 times so the peas aren't coated in green sludge)
empty slow cooker into the foil trays and place back in the fridge once it's cooled.
mash 1-2kg of potatoes.
add a layer in to each foil tray..
Shepherds pie for 1-2weeks for about 50minutes of active work and probably cost you 10-20 quid.
use foil trays so you can heat them in the oven and get a crust on the mash
or just use plastic if you don't care and will microwave them.
you can whack up 5.5 litres of curry or whatever so easily the same way and it's way less effort than you would imagine.
often made litres of thai curry sauce or pasta sauce in a huge wok too (bigger than any pans I own by volume)
if you start to get bored of rice/pasta you can just add it to oven chips etc
