How to Make It
Preheat oven to 450°F. Toss together chicken thighs, radishes, olive oil, and spice blend on a large rimmed baking sheet until evenly coated. Spread in a single layer. Roast in preheated oven until an instant-read thermometer inserted in thickest portion of chicken registers 160°F, about 30 minutes. Divide arugula evenly among 6 plates, and top with chicken, radishes, and pan juices. Sprinkle with salt to taste.
