Hi (again)
@AlexMagd !
I'm unable to cook at the moment. I'm not bone-idle (well...), but I can't stand for more than 2 minutes which means I have to zip about the kitchen on an office chair, meaning I can't safely stir pots and lots of washing up is very difficult to get done. On top of that, I'm moving house and have about 300 other reasons why bouts of cooking are beyond my capabilities.
BUT...
Slow cookers are amazing inventions and only need attention once an hour, and will turn out - with even the most basic of abilities - plentiful, healthy meals that you can munch happily away on. Plus I'm a big fan of throwing lots of veggies into a (disposable) oven tray (onions, cauli, peppers, mushrooms, sprouts, courgettes - anything, really) topping that with some meat (belly pork works well, chops, chicken breasts wrapped in bacon), dosing the whole lot with garlic salt and olive oil and then forgetting about it for 90 minutes. (If you use and reuse the tray, you'll get a delicious stock of meat and veg juices collecting at the bottom that will only enhance future foods. I reuse my trays up to 4 times)
Smaller cuts of meat will cook faster, and in a typical oven tray you can easily fit enough food for 2 people to be happily sated for a whole evening at least.
Other "cheats" include a massive bowl of tuna-mayo in the fridge, with dollops being added to those salads that come already in the bowls - that'll last you a good few days. Lots and lots of ham, egg-mayo, cheese. Occasionally I'll cook off an entire pack of bacon (in the George Foreman) and shove the lot in a food bag in the fridge to make for quick breakfasts. You can also boil eggs well in advance and they'll keep in their shells for up to a week.
Anything fatty will fill you up super-fast (I find I can only eat a small amount of cheese these days). Dry spices are your friends - experiment with Jamaican Jerk, Chinese Five Spice, Mixed Herbs. Don't forget, also, that a pint of full-fat milk will fill you up on the hop, too.
Final thing is snacking - a relatively good lunch will mean I'm not up for a heavy dinner, so will cheerfully tuck into berries and cream (if you use frozen berries, you get a delicious, weird kind of ice-cream), celery and brocolli with a dip are great (read the labels on these - hummus and onion and garlic have surprised me in the past), especially with a bit of ham, Peperami and a couple of Babybel.
You can also enjoy things like pre-packaged cauli-cheese, though I do my own super-easy version now, at a fraction of the cost for four times the amount:
Glass oven-proof bowl
Cauli florets
Bacon lardons
Double cream
Parmesan, cheddar
Garlic Salt
Oven
An hour of doing other things
Cheese on top when finished, under the grill to brown.
Put it in your face.
Don't forget there's a thousand ways to add variety and flavour to a basic, no-fuss diet, too - olives, pickles, balsamic vinegar, Marmite, cheap meat cuts (braised beef in the oven with red wine, peeled shallots and mushrooms), nut oils (Balsamic and sesame oil makes the BEST in-a-rush salad dressing), lemon juice etc etc
I felt much the same as you at first - "How on Earth am I going to manage such a sweeping change when I can barely stand, can't extend my food budget and have no time to spend on this?"
Make friends with your oven.
