Homemade FREE soup

So I made this really easily, and had it as lunches for two days of the week, can also keep as snack food when having a rough day. Believe me even if you thicken it up with some Syn'd cornflour or maybe just more potato and blend it, filling yourself up with soup is a great cure for a moment when you feel like giving in!

Leek and potato (bought mine for 50p ready bagged and chopped)
Ham, chopped
Vegetable stock
Water

Boil for 20-30minutes, and voila!
