2. Roast for about half an hour.
3. Meanwhile, gently fry the onion and garlic in a little olive oil or margarine for about 10 mins, then top up with about 300 ml / 10 oz of boiling water and add the sun-dried tomatoes (or tomato puree), the bay leaves, lemon juice, spices (if using) and sugar. Simmer for about 15 mins.
4. Remove the bay leaves and then hoik the sun-dried tomatoes and most of the onion out using one of those nifty spoons with holes in. Transfer to a blender and whizz for a minute.
5. By this time the stuff in the oven should be nicely roasted. Add it, oil and all to the blender and whizz for a bit longer, then pour this mixture back into the soup pan and give it a good stir. Can be served with a pretentious swirl of soy milk in it if you like.
