1. Cut all the vegetables into 1-2cm chunks.  

  2. Heat the oil in a large lidded pan.  Add the vegetables (including garlic, if using) and cook, stirring occasionally for 5 minutes. 

  3. Add all the other ingredients, bring to the boil and simmer gently with the lid on until thickened and the vegetables are tender.  This will take 20-35 minutes, depending on the size of your vegetables.  Add more water if too thick.

  4. Serve in bowls, with your favourite breadsticks or use it to fill a jacket potato.
