Heat olive oil in large saucepan over medium heat and cook garlic, stirring frequently, until just golden, about 3 minutes. Stir in remaining ingredients. Bring to a boil over high heat. Reduce heat to low and simmer covered, stirring occasionally, until sauce is cooked, about 30 minutes.
Blend sauce with immersion blender or in blender until desired consistency. Makes enough sauce for 2 to 3 pizzas.
