  • 3 Tablespoons red wine vinegar

Herb Salsa

  • Finely dice shallot. Place in a small bowl, cover with vinegar, and allow to sit for 15 minutes.
  • Finely mince 1/4 cup parsley leaves. Combine in a separate small bowl with olive oil and a hefty pinch of salt. 
  • Just before serving, use a slotted spoon to add the shallot (but not vinegar) to the parsley oil. Stir and taste for salt, adding more vinegar if desired. Serve on top of and alongside cooked fish.
