An example basket that covers it

- 0 kg of pasta, rice or grains
- 0 packs of crackers or biscuits (200 g)
- 0 jars of peanut butter (350 g)
- 0 bags of dried fruit or nuts (200 g)
- 0 AA batteries for torch and radio
The basket is only an example: choose food you already eat so you can use it up in rotation. Pasta and rice need extra water and a way to cook.
