In a sauce pan at medium heat, add the olive oil and cook onion and garlic for 3-4 minutes. Add the white wine and continue cooking 1 minute.
Add the rest of the ingredients, season with pepper then stir well. Simmer for 15 minutes while stirring often.
Remove from heat and blend. Let cool down entirely before using on your pizza ! I suggest freezing the sauce in ice cubes. A ice cube is about tablespoon and I usually use 2-3 tablespoons for a medium pizza.
