Stir all the vegetables and chicken stock and tomato sauce. Bring to the boil, lower the heat, half cover the pan and simmer gently  for about 15 minutes or until the vegetables are just tender. Add more stock  or water if necessery.
Remove the pan from the heat and stir the basil. Taste for seasoning.
