Add the chopped parsley, garlic, oregano, red chili, red wine vinegar, salt, and pepper to the bowl of a food processor. Process until finely minced (take care not to turn it into a thick paste from over-processing).
Add the olive oil and gently mix to combine.
It is best to let it sit for 15 minutes, but if you can, up to two hours.
Store in an airtight container in the fridge.
It can be used as a marinade, a finishing sauce, or a condiment.
Great on grilled steak, pork, fish, shrimp, or vegetables.
