Zest the oranges in strips and reserve for garnish. Slice the oranges into thin rings. Place the orange slices, arugula, fennel, red onions and olives in a large bowl and toss. Toss with the olive oil and lemon juice right before serving. Season the salad with just a touch of salt and pepper. Use the reserved strips of orange zest to garnish the plate.
