1. Preheat broiler.
2. For the salmon: Line a baking pan with aluminum foil. Coat foil with cooking spray. Whisk miso, mirin, soy sauce and ginger in a small bowl until smooth. Place salmon fillets, skin side down, in the prepared pan. Brush generously with miso mixture. Broil salmon, 3 to 4 inches from the heat source, until opaque in the center, for about 8 to 10 minutes.
3. For the cucumber salad: Wash and slice the cucumbers paper-thin. Squeeze out excess liquid and place in a medium bowl and toss with soy sauce, rice vinegar and sesame seeds.
4. Arrange cucumber salad on plate. Place broiled salmon on top. Garnish with scallion, sesame seeds, cilantro or parsley and drizzle with olive oil (optional).
