Ingredients

3 tablespoons olive oil 

1 large onion, chopped 

3 cloves garlic, chopped (about 1 tablespoon) 

Salt and freshly ground pepper 

2 cans (28 ounces each) diced tomatoes 

1/2 teaspoon dried thyme or Italian seasoning

Preparation

Heat oil in a large saucepan over medium heat. Add the onion, the garlic, 1/2 teaspoon salt, and 1/4 teaspoon pepper, and cook until softened, about 5 minutes.

Add the tomatoes with their juice and the thyme; simmer, stirring occasionally, until the sauce has thickened, 20 to 25 minutes.
