winter growing - is there anything I can start now?

I have five big raised beds, and only started gardening about 6 months ago, so have never grown anything through a winter.

Is there anything I can start now, that will survive the cold?  It makes me sad to see my raised beds mostly empty (apart from some ready-to-pull carrots, some herbs and some cabbage/broccoli that doesn't seem to be doing much).

Or should I just accept that it's too cold to do anything just now. 

I've got kale on the go, that seems to be doing fairly well in a pot, but any other suggestions would be great.

couple of suggestion would be to go for winter onions (still time)
aquadulce broadbean - probably a wee bit late... but you can always give it a miss as they always think it is a waste trying in this forum
other than that it is just mugs of tea after tea after tea...... (or whisky...)

I tried beans earlier in the year, but I only got a handful - where I live is quite exposed and I think the rubbishy summer weather (lashing rain/gales) was too much for them!

Never mind.  I'll concentrate on my non-edible plants for now, hoping to get some colour in the garden as early as possible!

Hm - I may as well have a bash at it - nothing ventured...
