I love a roasted soup. Very easy to make and very little fuss. Garlic is especially good after roasting as it takes on a beautifully sweet and mild flavour.
Roughly chop about 8-10 tomatoes, 4 sticks of celery and a small red onion. Place in a roasting tin with 2 whole bulbs of garlic (remove the skins but leave the cloves whole). Season with salt and pepper. Stir in a little olive oil and sprinkle with some fresh thyme. Roast at 180 degrees for 45mins to an hour, stirring occasionally.
