In a Dutch oven, heat 3 tablespoon olive oil over medium heat.
Add onion, garlic, granulated garlic, and granulated onion.
Cook until the onions turn translucent.
Stir in tomato paste and cook until it darkens significantly.
Crush whole tomatoes by hand and add them to the pot. Mix well.
Add oregano, salt, and pepper to taste.
Reduce heat to low and simmer for 1 hour, stirring every 10 minutes to prevent burning.
After 1 hour adjust seasoning if needed.
