In the meantime, add the oil to a large skillet over medium heat. Add in the onion and sausage. Cook until sausage is brown and no pink color remains.  Add in the garlic and cook for 1 minute, or until fragrant..

 

Add in the tomato paste, tomatoes, broth, salt and pepper. Cook, stirring occasionally, until the tomatoes begin to burst and give off their juices, about 10 minutes.
