Orange-Fennel Vinaigrette makes even a simple plate of greens memorable. The orange juice provides a subtle tannic acidity while the fennel gives this dressing a slight licorice quality.
Combine orange juice, vinegar, fennel seeds, orange rind, salt, and pepper in a bowl, stirring with a whisk. Gradually add olive oil, stirring constantly with a whisk. Drizzle over Bibb lettuce.
