I have run my food prep right down to zero and I'm about to restart.
This tone atound im thinking about we we eat, not what we should eat. So just going to prep basics that we will eat anyway.
Dried pasta
1kg sack of rice
Tinned tomatoes
Passatta
Baked beans
Chicken peas
Lentils
Tinned soup
Instant noodles
We are 6 so I'd aim for max ten of each tin / packet and always have a sack of rice.
I but two items a week when I remember, add it too a list with its bbf date. I normally have to oat mils and two long life milk cartons in..
I only prep for a month or so. It's more than enough to cover bring snowed in ( rural) and being caught out at the very beginning of covid.
I have got usb torches for all six of us. Ideally I'd buy a few more each year as they do go wondering.
About 6 litres of water that's probably off by now. We had a major water outtage recently and I think you need two days of water to drink. Beyound that uou need to go out and collect it. Our water collection point was simple enough
Lots of power banks always fully charged and little lamps that plug into them.
I did mean to get a few of the light bulbs that charge up to but never did. One in the living room and hall would be handy
