Fruit & Veg In Shady Areas

I have an area of the garden against a wall, with a overshadowing it. There is a decent sized area that does not get a great deal of sun. Is there any fruit of veg that can grow in this area (shaded, most of the day).

 

My raspberries grow really well in the shady part of the garden, as does a blackcurrant bush

 

I think any types of salad/leaf vegetables will grow fine, they don't need much sun anyway. Fruit I'm not so sure about, since they usually need full sun to grow.
