In a large saucepan, heat a little oil and add the onion and garlic. Saute gently on a medium heat until softened.
Add the tomatoes, tomato puree, lentils and water. Cook on medium heat stirring occasionally until it comes to the boil.
Once boiling, reduce the heat and simmer for 20 minutes.
Add the basil and stir through.
Remove from heat and blend to desired consistency.
Allow to cool to appropriate temperature for baby, test and serve.
This is a great way to introduce tomatoes to baby and lentils are a good source of protein. Add more vegetables to alter flavour and add extra nutrients. Serve with fingers of wholegrain toast when baby is accepting finger foods.
