Chop white part of leek and place in the bowl with the garlic and sliced bacon and oil. 2 minutes, 100o speed 1. Add rice and wine. Cook 2 minutes at 100o reverse speed soft. Add stock and water, cook for 7 minutes 100oReverse, speed soft. Add the halved tomatoes and cook a further 10 minutes as above.
