Salty, some fruit and veg are cheaper than others. I buy for a fortnight at a time, and this fortnight I've bought:
Fruit: 1.5 kg bananas, 3 bags of apples, punnet plums, 500g grapes, bag 10 satsumas.
Veg: 2.5kg potatoes, cauliflower, savoy cabbage, kilo courgettes, broccoli, huge butternut squash, punnet tomatoes, 750g carrots, leek, 1.5 kg onions, red onions, 4 cucumbers, an iceberg lettuce, celery, 1 kg frozen sweetcorn.
I think that's a normal amount of fruit and veg. I stick to £50pw (so £100 per fortnight).
