Lamb and barley soup

1 Cook barley in a saucepan of boiling water for 10 minutes. Drain.

2 Heat oil in a large heavy-based ovenproof pan over a medium heat. Add onion and celery. Cook, stirring occasionally, for 5 minutes. Turn heat to high, add lamb and garlic. Cook for 5 minutes or until lamb is browned.

3 Add barley, tomatoes, stock and water to pan. Bring to the boil. Reduce heat to low, partially cover, and simmer for 1 hour or until lamb is tender. Add water if soup gets too thick. Serve with a sprinkle of rosemary.
