Some side dishes are so good they deserve their own share of the limelight. These (mostly vegetarian) stars-in-the-making all make good accompaniments to a meaty main course, but they're ready to move centrestage too. Nothing could be simpler than a mixed citrus and chickpea salad. For a taste sensation, go for mushrooms, fresh green tarragon and pearl barley, while if spectacle's your scene, you'll love these Parmesan and polenta crusted artichokes with mint and honey.
