Add all of your ingredients to a small bowl or salad dressing shaker. Whisk until fully emulsified, or cover and give it a good shake until emulsified. Salt and pepper to taste.
That's it. Top your Italian sub sandwiches, cold cuts or salads with the dressing and enjoy!
Notes
You can use any vinegar that you have on hand for this dressing. White wine vinegar, balsamic, and apple cider vinegar are all great options.
