This one has some vegetable soup recipies towards the bottom, working on a basic principle of 'hurl vegetables into pot. Add something meaty. Boil. Lots'. And there's this:
Ingredients. Dry bread, broken in bits, water, salt and pepper, an onion and a little fat.
Soak the bread in boiling water for a few minutes, add the onion sliced and fried in the fat; salt and pepper well.
There's a recipie for the end of a store cupboard.
