Tomato Sauce with Sauteed Vegetables and Olive Oil

I didn't know how to make a good tomato sauce until I bought this book....now I know how to make several. I think of this one as my Winter sauce as it starts with a heartier base of onions, celery and carrots sauteed in olive oil before canned or fresh tomatoes are added and the sauce simmered.

It has an intense, fresh tomato flavour with a richness supplied by the olive oil; the natural sweetness of the fruit and sauteed vegetables is brought out in cooking...no need to add sugar or any flavourings apart from salt and pepper to complete this fabulous sauce, a staple in my home.
