The addition of scallions/spring onions to the dressing adds a subtle but noticeable flavor and is worth trying. I put all the ingredients in my food processor which made the dressing very creamy and the scallions gave off a stronger flavor than if they were just chopped.
1 tbsp. Dijon mustard
1 tbsp. honey
1 tbsp. red wine vinegar
3 tbsp. olive oil
1 bunch of scallions (about 6)
Place ingredients in food processor in order they are listed. Make sure the scallions get well processed.
Makes 1/2 cup.
