Finding vegan-friendly salad dressings is definitely hit or miss. Many creamy salad dressings like ranch and bleu cheese contain dairy and therefore, are not vegan friendly. Caesar salad dressing is also typically made with anchovies and eggs and is also not vegan-friendly. Oil based salad dressings and vinegars are usually vegan-friendly, but always check your labels for sneaky inclusions of dairy and eggs. Or, for best results, make your own vegan salad dressings at home.
