Chop the herbs. Finely chop the mint and parsley by hand for the best texture.
Mix the base. Transfer the herbs to a bowl and add the garlic, vinegar, salt, and red pepper flakes.
Add the olive oil. Slowly stir in the olive oil until the sauce is loose and spoonable.
Season and rest. Add black pepper to taste. Let the mint chimichurri rest for 10 to 15 minutes to allow the flavors to meld, before serving.
