Try doing your shopping about an hour before the supermarket closes and look for the reduced stuff.
Also check out your local food market, again, about an hour before closing time - last week I got 2 large punnets strawberries, 3 medium punnets raspberries, 2x blackberries, 2x blackcurrants & 2x blueberries all for £1 per fruit. Also got huge bags of tomatoes, mushrooms and quite a few different veggies all for £1 each. I ended up spending around £10 but the whole lot would easily have cost me between £20 - £30 if I'd bought them in the supermarket.
Also try economising with your recipes. I cook for 3 adults in our house and when I use a 1 lb pack of mince I can make 2 meals out it and both meals yield around 5 or 6 large portions. My husband and son are both big meat lovers and they have no idea that there are more veggie ingredients than meat in the meal.
I fry 1 lb mince with loads of mushrooms and onions and then half the mixture - freezing half of it for a meal later in the week. If I make spag bol, I add half a chopped yellow, red & green pepper, several grated carrots, a grated courgette and half a grated aubergine (peel the aubergine and courgette first - if there's no skin on it then it just cooks down into the smartprice toms and passata that I use and there's no trace of it so they can't complain,
)
A handful of red lentils thrown into any casserole type dish will bulk it out.
If I do mince & onions then I will add lots of finely dice carrots and about a quarter of a bag of smartprice frozen peas, a few lentils to thicken it so I don't use as much gravy granules (extra syns) and don't forget the beef stock cubes to give it a meaty flavour. My wok is almost full but I've only used 1/2 lb mince and I still get around 6 large portions from this.
Its also worth checking out the moneysavingexpert forums for lots of ideas how to save money on your shopping and for cheap recipe ideas.
