Well - I went for the chicken in the evening in the end, just a tiny bit to go with the cooked chickpeas in the fridge that really did need using up. I had forgotten about them.
So today went like this with a few changes from the plan
B: porridge with sugar and natural yogurt; pear Total 13p
L: Really nice tomato and lentil soup with some fresh wholemeal granary bread* Total 14p
D: Chicken and chickpeas in a creamy sauce with rice; natural yogurt with a bit of sugar Total 58p
Snack: salted peanuts: 14p (I know - bad me!)
I had £18.22
I spent 99p
*technically the bread was free because what I do is reckon ten slices from one of my dear little loaves and price them accordingly, so if there's a crusty bit left, that's free! It's not easy to slice such fresh bread (are you jealous yet); I can never be sure how it will go so, for consistency's sake, I do it like that!
