About 1/2 teaspoon (Adjust to your desired level of saltiness)
Put all of the ingredients into a food processor (you can also use a blender) and blend. Blend until the garlic is very fine.
Taste it and add salt and red chili pepper as desired. Transfer it to a glass bowl and then let it rest at room temperature for 2-3 hours for the flavors to blend.
Italian parsley is quite fluffy so push it down firmly to make the 1 cup serving.
You can add a small amount of finely chopped onions and lemon juice if you'd like. You can also add some squeezed lime juice, which is also delicious.
Story Behind this Recipe
We had some chimichurri sauce in a restaurant and my family loved it. I tried making various versions of the recipe and I eventually arrived at this. It seems like you can also make this with a herb mix from Argentina. I had my friend from Argentina send me one.
This recipe uses American style cup measurements so 1 cup = 240 ml. Adjust the amount of red pepper to your liking (We add a little extra in my home). It's best when it's a bit spicy! Depending on what kind of salt you use, the actual salty flavor will vary. So start with a small amount and then add more as necessary.
