Add Italian Seasoning and cook additional 30 seconds.
Add in diced tomatoes and juices, pepper and salt if needed.
Stir and allow to come to a gentle simmer.
Simmer for 15 minutes on low, stirring and mashing down tomato chunks with a wooden spoon, until desired thickness.
Use immediately or store covered in the fridge.
Recipe Notes
Makes enough for 2 pizzas.
Double recipe to use a 14.5 oz can of diced tomatoes. Extra sauce is stores well covered in the fridge for a week.
My Italian Seasoning has salt and so I generally do not add more.
