This salad of arugula and watercress, dressed with a light orange-poppy seed dressing, makes the perfect nest for the individual carved racks of lamb. This dressing would also be terrific tossed with a light luncheon salad of grilled shrimp, scallops, and baby greens.
To make the dressing: In a bowl, whisk together honey, grated orange zest, orange juice, poppy seeds, vinegar, and salt. Gradually whisk in olive oil. Toss watercress and arugula in a large bowl. Before serving, add just enough dressing to coat greens; toss to mix well.
To serve: Place a nest of greens on each individual dinner plate. Top with carved lamb rack.
