I'm having:
Frozen fish fillets with frozen mixed veg and frozen onions, microwave 4½ mins with a bit of hot water. Drain water.
Microwave rice, 2 mins in pouch.
Tip rice into veg/fish dish. Add flavouring (fish sauce, soy sauce and lemongrass in my case).
Break up fish with a fork, check it's cooked, microwave another minute if not.
Also works with small chicken pieces if not frozen.
Last night I had:
Baby new potatoes, cooked in microwave 3 minutes.
Added frozen veg, back in microwave 3 minutes.
Pork loin steaks, coated in yoghurt with harissa and baharat spices, air fried 10 minutes while veg cooking.
You can ring any number of changes with this - different veg, rice, different meat, different flavourings.
Tomorrow will be:
Oven chips, air fried 10 mins, with steak in air fryer after 5 mins.
Bagged mixed salad with tomatoes.
Any day:
Baked potato: microwave 5 mins, air fry 5 mins
Can of tuna, salmon, whatever.
Bagged salad or microwaved frozen veg.
Fallback dinner:
Tin of curry, microwave rice, I might add other veg to curry.
I've only got the microwave & air fryer! If you have a proper oven and hob, you can really broaden your scope.
Also don't underestimate the slow cooker - put everything in and start it 4+ hours before dinner.
I don't prepare veg as have no energy, and am careful of the nutritional content of my fast, easy dinners :)
