And lentils. You can cook lentils with water and salt and nothing else, and they come out edible and nice enough, if unexciting - but they serve as a fantastic canvas for adding small amounts of other long-lasting things (stock, oil, herbs, spices, cured meat) which add interest.

Which is why my no-deal Brexit survival stash is a couple of kilos of Puy lentils, a bottle of olive oil, and a box of stock cubes!

With peanut butter, honey and other things, it's surprisingly tasty

Yes, but we need a variety of such foods.
