The making of a great vinaigrette salad dressing starts with the ingredients. Our main key ingredient in this dressing is the imported Greek extra virgin olive oil. Other key ingredients are only natural herbs and spices, with no artificial flavorings or preservatives. This vinaigrette recipe was given to me by my father-in-law, who ran a restaurant for 43 years. I enjoy this vinaigrette recipe so much that I bottle it to provide it to you.
