Assemble the salad. Add all of the salad ingredients to a large glass bowl (or well-oiled wooden salad bowl). Toss to combine.
Prepare the dressing. Add all of the dressing ingredients to a glass jar with a lid. Shake well, or use a small milk frother to emulsify the dressing.
Combine. Pour the dressing over the salad, and toss once again until well coated.
Adjust. Taste and add flaky salt and pepper as desired.
Serve. Scoop portions into individual bowls to serve, garnishing with additional fresh basil (if desired). If preparing for meal prep, transfer to an airtight container and refrigerate for up to 4 days.

Feel free to swap the salami for one of these options in this recipe if desired.*Vinegar types: White wine vinegar has the most subtle flavor, but red wine vinegar can be used instead if you prefer a stronger taste. White vinegar is too strong of a flavor and not recommended.**Dijon mustard: The original recipe uses dry mustard powder, which can be found in the spices and seasoning section of your local grocery store. You can substitute dijon mustard if you can’t find mustard powder.
