Begin by heating some olive oil in a large skillet over medium heat.
Once the oil is hot, add the minced garlic to the pan and sauté until fragrant – about 1 minute.
Stir in the oregano, black pepper, and salt into the mixture and continue to cook for an additional 30-45 seconds.
Add the tomatoes to the skillet, crushing each one with a wooden spoon as you add them into the saucepan.
Bring the sauce to a low boil and reduce heat to allow simmer for about 25 minutes or until it has reached the desired thickness.
Give your sauce a taste test and adjust the seasoning if necessary.
When the sauce is finished, use it immediately or transfer it to an airtight container for later use.
