Roasted vegetables with skorthalia

Skorthalia is a rich and creamy Greek sauce-cum-dip made with bread, almonds, lemon juice and more than a hint of garlic. You can use raw garlic, but to make the most of the oven while cooking the vegetables, the garlic is roasted here for a more subtly flavoured sauce. Greek basil has smaller leaves than the regular variety and a slightly stronger flavour, but you can choose whatever is to hand, or indeed use fresh thyme, oregano or marjoram.
