I’ve usually made my own batches of tomato/mince-based sauce for lasagne, spag Bol, etc. But nowadays it contains a lot more finely chopped veg and red lentils, so semi-veggie.
It was brought home to me last November just how much sugar is in bought tomato sauces/soups, etc. I was making 8 (!) litres of tomato and red pepper soup for Gdcs’ school fair, and until I read the list of ingredients on both a jar of ready-made pasta sauce and a tin of Heinz tomato, I hadn’t realised just how much sugar was in them.
Afraid to say I did add sugar to my soup - no use going to all that trouble if it wasn’t going to taste ‘right’ for outdoor fair-goers on a cold day.
