Don't you realize that those are very expensive? Cook rice, pasta or potatoes for your calories and you could get by on that amount without going hungry. I lived on that amount for years, you'd get around 4000 calories if you just bought cheap things which is more than you need so you can buy lentils, meat, fish and vegetables for the rest which is enough to get all nutrients you need. Might not get 100% optimal diet on this, but it is healthier than what most eat.

In Finland, where groceries are quite expensive as it is, you can get an enormous bag of white toast for about an euro. Same for a can of beans, a regular can is about 60 cents. If they're going out of date they can be up to 60%. Rice or potato is going to be more expensive.
