Mustard, vinegar and chives bring their lively flavors to this simple salad.
To make dressing: Combine oil, vinegar, mustard and sugar in a small glass jar with a tight-fitting lid. Add water and shake until smooth. Add chives (or scallion greens) and season with salt and pepper; shake again.
To make the salad: Just before serving, toss salad greens with the dressing in a large salad bowl. Arrange carrots, cucumbers and croutons on top.
