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