Spicy arugula with sweet oranges, what a nice combination of sweet and savory. I always like salad recipes with that contrast.
2 large fresh fennel bulbs, trimmed, each cut vertically into 12 wedges with some core attached
6 fresh thyme sprigs
6 tablespoons extra-virgin olive oil, divided
1/4 cup Sherry wine vinegar
1 tablespoon Dijon mustard
4 oranges, all peel and white pith cut away, halved vertically, thinly sliced crosswise
2 (5-ounce) packages baby arugula
Preheat oven to 400 degrees. Combine fennel wedges, thyme, and 4 tablespoons oil in large bowl; toss to coat. Arrange fennel, cut side down, on large rimmed baking sheet. Sprinkle with salt and pepper. Roast until fennel is tender and brown, turning once, about 40 minutes. Discard thyme sprigs. This can be prepared ahead of time and stored. Use at room temperature.
Whisk vinegar, mustard, and 2 tablespoons oil in large bowl. Season dressing with salt and pepper. Add fennel, orange slices, and arugula. Toss to coat. Transfer salad to large shallow bowl.
I love arugula in salads. If you do too, try another one, like this Boston Lettuce and Arugula Salad with Tangerines .
