Open a can of whole peeled Marzano tomatoes. Add them to a medium sized sauce pan. Smash the tomatoes with a potato masher or break into small pieces using your hands.
Add olive oil, garlic, basil, salt and pepper. Turn heat to medium and cook for 20 minutes. Season with additional salt and pepper if needed.
Notes
This sauce is a chunkier type of pizza sauce. If you'd like it smoother, use a hand blender to make oit smooth at the end of cooking time.
