Pearl barley is quick and simple to cook but reassuringly nourishing. Usually added to soups and stews, it's equally delicious tossed through a salad for added texture and flavour. I love the way it soaks up the dressing. First, however, toss your vegetables in a mix of spices then roast in the oven. Once done, add the spinach, barley and fresh, flavoursome dressing, and you're away.
