With flavors of anise, tarragon is one of our favorite soft herbs. If licorice isn't your favorite, swap out the tarragon for fresh basil or dill. This healthy salad dressing is particularly good on escarole.
Combine oil, vinegar, onion, tarragon, honey and salt in an 8-ounce mason jar. Shake vigorously until combined.
To make ahead: Refrigerate for up to 1 week; shake before serving.
