It's clear from this thread, and entirely unsurprising, as we are all human, that most people see the world as they live it.
Those who are able to cook think everyone should be able to cook. Those who learnt cooking and budgeting at school think it should be taught there, and if those who well by learning what they see as more important subjects think that others should also pick it up as they go along. Those whose mothers taught them think the skills should be taught in the home and so on.
It may seem obvious to those with a fridge, freezer, microwave and soup maker that veg can be bought in bulk or cheaply when 'on the turn' and made into batch cooked meals, and equally obvious to those without a local market or transport to get to one that this isn't an option. And so it goes for that side of things, too.
What is, however, very clear, is that the idea that you can cook anything other than gruel for 30p a portion is ridiculous, and that the fact that some might have to try to get as close to this figure as they can to fend off hunger is utterly shameful.
