In my cost-cutting drive, I have got my lunch at work to under 50p. However, having the same (or similar) thing for lunch every day gets a little boring, so what alternatives can people suggest. The only "rules" are: Cost no more than 50p/day Contain no more than 1.5g of salt or "salt equivalent". My current solution is: 400g can of Heinz soup - 3 for £1 from tesco and sainsburys Bread roll - 15p What alternatives can you suggest?
