Afterwards I asked the guy why bottled sauces and "traditional" recipes call for oregano, basil and "Italian spices"? He says to me "because that is the only way you can make a 99 cent tomato have any taste, You have to use the whole Italian tomatoes. When you crush a tomato and liberate the seeds, it loses its sweetness".
I totally agree! Right now I'm looking at a very good Italian cookbook, and their basic sauce recipe is almost identical to yours. Only they add finely chopped onions. It sounds great and I will make it when my tomatoes are ready.
