The whole Fray Bentos pie for a quid thing has set me thinking.
I reckon two of us could eat healthily for less than a tenner a week.
I can get a bag of veg and teddies, that would easily last a week, for £2 from the farm across the road. You don't need meat every day and you could stretch mince and a chicken out over a few meals. I can catch Pollack, Whiting and Mackerel in season, within half a mile of my house.
Porridge is cheap and healthy for breakfast.
With a bit of judicious purchasing, I reckon it could be done.
Might give it a try sometime.
