Method

1. Heat the oil and pan fry the onion for 5 minutes without browning; add the tomato to cook for 2 minutes. Pour in the crushed tomatoes, spoon in the purée and stir well.
2. When the mixture is simmering, add the garlic and lemon juice and cook slowly for 30 minutes. Stir occasionally. Remove from heat to cool.
3. Pour tomato stew into a large baking dish or divide evenly into 4 ovenproof dishes.
