Just out of curiosity then, coming back to
Zak's poached egg soup recipe, and with a bit of Tesco.com browsing:
1 kg potatoes, 69p. Say 10p per bowl of soup, just for argument's sake.
1 kg onions, 69p, Say 10p again?
Paprika, £1 per jar, so say 5p?
10 stock cubes, 15p, so say 3p
Tinned tomatoes, 31p per can, so £1.24 total
Tomato puree, 34p per tube, so say 10p.
Six eggs, £1.34, so two eggs equals 46p.
The total spent is therefore £5.46, of which, roughly £2.10 is used to make the soup, which would make at least three meals, give or take an egg or two.
You should submit that one to Unicef Zak. It's way better than most of the recipes that they list. I guess the problem is that at roughly 70p per portion, it only leaves another 30p for all the rest of your food and drink for the day, and doesn't allow for much variety.
It's quite a challenge Rispainfarm. I do hope you're going to keep us updated with progress!
