Marinated Red Onions

•   1 small red onion
•   ¾ cup Extra Virgin olive oil
•   1 tablespoon dried oregano (not ground)
•   1 tablespoon red wine vinegar
•   1 to 2 teaspoons of high-quality balsamic vinegar (optional but highly recommended)

• Thinly slice the red onion and place in a low bowl.

  In a separate bowl, stir the olive oil, red wine vinegar, balsamic vinegar, and dried oregano together to combine well. Pour the mixture over the onions, making sure they are submerged.

  Let sit on the counter at room temperature to marinate for 12 hours before using. Keeps for 2-3 days unrefrigerated.

  **I sometimes omit the oregano and add a generous tsp of kosher salt**
