What I mean is, in terms of preparing fresh food e.g. peeling and chopping potatoes, carrots, cutting broccoli, courgette, etc are there any 'hacks' you use so you can prioritise the activity of preparing food on 'good' days and not have to deal with it on the 'bad' days.
Cooking meals in bulk e.g. casseroles, curries etc is not a problem once the food is prepared (personally I whack everything in the slow cooker and later that day I have 4 or 5 meals).
One that I have recently started to use is chopping onion - chopped onion can last up to a week when refrigerated and in an airtight container.
For a long time I have cooked at least 2 days worth of veg, mashed potato - if I know the next day is a busy one, I'll have a nice meal ready for heating up in the microwave.
I understand you can buy prepared veg in the supermarkets, but 1) it's expensive, and 2) I have tried some and mostly the taste isn't good (I know, it's there for convenience).
I live on my own and can prepare food safely, however on the really bad days it can be a battle/mess in the kitchen! 😂
