In a small mixing bowl, whisk together the olive oil, 1 tablespoon of the white grape vinegar, minced garlic, sea salt, oregano, red pepper flakes, and smoked paprika.
Stir in the finely chopped parsley until evenly combined.
Taste the sauce and add the remaining tablespoon of vinegar if you prefer a brighter, tangier flavor.
Allow the Chimichurri Sauce to rest for 10–15 minutes before serving so the flavors can meld together.
Spoon over grilled meats, chicken, seafood, roasted vegetables, sandwiches, or grain bowls.
