Surviving a week on £30...

[LadyOfWaffle]

Dunno how but there is only £90 in the bank, £15 has to stay in for the internet bill, at least £40 needs to be put aside for four days of petrol for DH to get to work , which leaves £30 I can withdraw (cannot take out £5s). First of all it sounded ok, but wrote a list with nappies - £4, wipes - £5, then £1.30 for 4 pints, for 7 days is £9.10... which is leaving about £10 for food! Wipes are non neg., cheaper ones rip poor DSs bum to shreds, obviously I will have to drink less milk but how do I do 7 days (DH, me and DS) for £30? Thanks sooo much if you can suggest anything!

easy white sauce - couple of desertspoons of cornflour or plain white flour, knob of butter, 2 cups of milk - microwave a minute at a time, taking out and whisking thoroughly every 30 secs/minute. Don't let it boil or it will thicken up too much. Add small amount of grated cheddar and large pinch of mustard powder (if you have it - brings out the cheesy flavour).

Can be refrigerated if you have some left over.
