What to sow in winter or early?

I've never done this, but might think about starting after Christmas -- you know , those days when you want to go the plot but better not leave the house or you'll be in trouble 

If you need a quick 'grow something' fix, try sprouting seeds like alfalfa, mungbeans, fenugreek.......

You can buy a special sprouting whotsit, but a jamjar with a clean cloth rubberbanded over the top works just as well. Soak your beans or seeds overnight, drain, then rinse morning and night with fresh water, making sure you drain well.

It's much cheaper to buy the seeds at your local health food shop than buy the special packs seed companies do. Or Indian shops often have very cheap bags of beans and seeds you can sprout.

Easy, cheap and good for you. Use in salads and stir frys  

How about a few sweetpeas if you must sow something. Mine are out in a cold uninsulated greenhouse and they're sprouting like there's no tomorrow  They don't seem to mind the cold.
