01 - Preheat oven to 400°F. Line a baking sheet with parchment paper and set aside.
02 - In a small bowl, whisk together white miso paste, soy sauce, mirin, sesame oil, honey, and freshly grated ginger until smooth and well combined.
03 - Brush the salmon fillets generously on all sides with the miso marinade. Let rest at room temperature for 10 minutes to allow the flavors to penetrate.
04 - Place the marinated salmon fillets on the prepared baking sheet. Roast for 12 to 15 minutes, or until the fish flakes easily when tested with a fork and reaches an internal temperature of 145°F.
05 - While the salmon roasts, cook grains according to package directions if not already prepared. Blanch the edamame, shred the carrots, slice the cucumber, avocado, and radishes, and thinly slice the scallions. Arrange all vegetables and toppings within reach for assembly.
06 - In a small bowl, combine rice vinegar, soy sauce, sesame oil, and honey or maple syrup. Whisk until fully blended. Set aside.
07 - Divide the cooked grains evenly among four bowls. Arrange edamame, shredded carrots, sliced cucumber, avocado, radishes, and scallions in sections around each bowl over the grain base.
08 - Place a hot miso-glazed salmon fillet on top of each assembled bowl. Drizzle with the prepared dressing, sprinkle with toasted sesame seeds and nori strips. Serve immediately while the salmon is warm.
