it’s not just about expecting poor people to be happy with cheese and broccoli pasta
You've somewhat spectacularly misunderstood my post.
Because, when people state they have an extremely low weekly spend, and it's queried, the typical answer tends to be none of the points you have made.
It's never "well, that's actually our budget, so that's all we can spend, and it might mean soup and a roll for two nights but so be it."
Or "I don't actually have the time to cook/don't know how to cook, so we generally have freezer food for dinner, and this is really cheap"
It's when people almost scoff "you spend how much?! I feed 8 of us for £40 a week I'll have you know, and it's very easy if you are an accomplished cook"
Then when you drill down into how on earth this is possible, a meal plan of "cheese and broccoli pasta" followed by "cheese and fried egg on toast" tends to be produced. Then it's like, "ohhhh, fine, I get it now, that's what you call a meal, well yes, you can probably produce that for £40 a week"
It's not "nonsense". If it was my preference, I could serve my family ham sandwiches for dinner all week, and it would probably halve my food costs. It is just somewhat misleading to compare that meal/cost to someone cooking a nutritional, balanced meal as cheaply as possible.
