To start, first roughly chop the onion. Peel and finely mince the garlic. Over medium to medium-low heat, cook the onions in the olive oil for a few minutes. Add the garlic and cook until fragrant. Then add the tomato paste and cook another minute or two.
Next, add the crushed tomatoes, whole tomatoes and the sun-dried tomatoes. If the sun-dried tomatoes were packed in oil, be sure to drain them first. Add the pepper, salt, oregano, sugar and balsamic vinegar. Stir well.
Let the tomato sauce come to a gentle boil, stirring often. Cover, turn the heat to low and let simmer for an hour, stirring occasionally.
