Red Onions are pickled with garlic, olive oil and Greek herbs. Herbed Pickled Red Onions can be their own ingredient in sandwiches, salads or serve on cheese and crackers. Where it does seem unusual to add olive oil to pickled vegetables, this recipe was inspired by the Greek pickled vegetables, toursi. This Greek pickled vegetable recipe includes olive oil.
