Italian dressing is a vinaigrette-type of salad dressing in United States and Canadian cuisine, consisting of water, vinegar or lemon juice, vegetable oil, chopped bell peppers, usually sugar or corn syrup, and a blend of numerous herbs and spices including oregano, fennel, dill and salt. Onion and garlic can also be used to intensify the dressing’s flavor. It is often bought bottled, or prepared by mixing oil and vinegar with a packaged flavoring mix consisting of dehydrated vegetables and herbs.
