Bacon and Cabbage Frittata paint

This beautiful sauce is best made towards the end of the summer when fresh tomatoes are plentiful, sweet and delicious. Oven-roasting tomatoes at low temperature concentrates their natural sugars, giving a sweeter and much more flavourful version – ideal when tomatoes are out of season. Making your own sauce also gives you total control of the ingredients with their quality and flavour.  The results speak for themselves – you will end up with a sweet, rich and velvety sauce. This homemade roasted tomato sauce just tastes so much better than the store-bought stuff – and it freezes great!
