If you want to try something a bit different, this is it! Don't worry if you think the portions look small; pearl-barley is very filling and the mushrooms are full of flavour. In other words, a little goes a long way. The original recipe came from supplement to a Sainsburys magazine, called 'The Best of Italy'. I've been hoarding it for two years and am really pleased I finally got round to making something from it (so many recipes; so little time)! Needless to say, I have made a few tweaks to the original recipe, which called for 1tbsp each of celery and carrot (how much is that?), so I added my own amounts. Other tweaks include less oil, different mushrooms, more garlic and lets add some cheese!
