Ingredients

2 tablespoons olive oil 

1 can whole Italian peeled plum tomatoes (2 pounds) 

3/4 teaspoon dried oregano 

1 1/2 teaspoons salt 

1/8 teaspoon freshly ground black pepper 

Preparation

Pour olive oil into a large skillet, and place over medium heat. Using your hands, squeeze tomatoes to crush them. Add to the warm olive oil, along with the remaining ingredients. Cook over medium-low heat, breaking up tomatoes with a wooden spoon, until the sauce is thick, 40 to 50 minutes.

Pass sauce through a food mill, discard the seeds, and let cool.
