We tend to go for starchy comfort foods as the weather turns cool and the days get dark, but we can still enjoy rich flavours and satisfy our appetites with lighter fare. This simple tomato sauce is sweet and slightly tart due to the addition of balsamic vinegar and makes a bright, full-flavoured pairing with salmon – but you can just as easily serve with chicken breast or even over whole wheat pasta. And I promise you will happily rub your belly when done.
