Pasta with Parma ham, asparagus and creme fraiche is lovely too.
I add the asparagus to the pasta at the end of cooking, so it's just one pan.
Bonus points as Parma ham and creme fraiche have a very long fridge life! Frozen broccoli works in it too.
Minestrone soup? Homemade and frozen in advance or a carton from the supermarket. Keep par baked baguettes in the cupboard for emergencies.
When I feel crap I like something I can eat with a spoon. I freeze homemade moussaka and Currys and suchlike in the Chinese takeaway containers. I have mini casserole dishes the same size, so I pop out the frozen block, put it in the dish, cover with foil and put it in my mini oven on low (160ish ) for 90 minutes. Zero effort and a healthy dinner! Set an alarm for when it's ready so you can nap, read etc with no worries.
I have noticed that a lot of Tesco ready meals are very low or no upf now, so if you know your bad time will last a while you could do an online order on the first day to stock up. I usually go for the veggie stuff as I think it reheats better. But there's loads of choice.
Tesco also do frozen 800g bags of paella, pasta, noodles and green curry. You add a few tablespoons of water and heat on the hob for 10 minutes. Veggies, protein and carb in one easy pourable bag.
Or scampi chips and a frozen corn cob for 20 minutes in the oven.
If you do get a grocery order, I also get those kids pure fruit juice boxes with a straw. Perfect size if you crave a sweet drink, or if you have frozen fruit, a good size for a smoothie too.
You'll not only want stuff that is easy, but also that you genuinely enjoy eating otherwise it's very easy to not bother at all and just get an Uber!
