Step 1

Preheat broiler. Stir together 1 tablespoon each soy sauce and honey in a large, shallow dish. Add fish; turn to coat. In a bowl, whisk together lemon juice, curry, remaining 1 tablespoon each soy sauce and honey, and oil. Season with salt and pepper.

Step 2

Place fish on a rimmed baking sheet and broil until cooked through, 5 to 6 minutes. Let cool slightly, then flake into large pieces. Toss lentils and scallion with half of dressing; season with salt and pepper. Spread yogurt evenly among 4 plates. Top with lentil mixture, arugula, and cucumber. Top with salmon and drizzle with remaining dressing; serve.
