Start by finely chopping the fresh parsley and garlic with a sharp knife or pulse them gently in a food processor.

In a medium bowl, mix together the chopped parsley, minced garlic, oregano, red pepper flakes, salt, and black pepper.

Pour in the red wine vinegar, giving everything a good stir to coat the herbs evenly.

Slowly drizzle in the extra virgin olive oil while stirring briskly to blend the sauce.

Allow the sauce to sit for 15–30 minutes before serving, encouraging the flavors to meld together.
