Take your preserved lemon and rinse. Remove any seeds from the lemon. Chop into small pieces.
Add the chopped preserved lemon, dijon mustard, and juice from 2 lemons into a blender or food processor. Blend together.
Add olive oil (while blending, if possible) in a steady stream. Blend for 15-30 seconds until dressing is smooth and all ingredients are blended together.
Notes
Preserved lemon should be rinsed and seeds removed before using in this recipe.
A blender or food processor works best to blend this vinaigrette. Cutting the preserved lemon into small pieces also helps them to all get blended into the vinaigrette.
