Preheat the oven to 450 degrees F.
For the salmon, whisk together the miso paste, lime juice, sesame oil, soy sauce, ginger, and honey in a small bowl. Slowly whisk in the olive oil.
Arrange the salmon, skin-side down, and season lightly with salt and pepper. Carefully pour the miso glaze over the salmon. Bake for 10 minutes, or until just cooked through.
For the slaw, toss together the cabbage, carrots, and cilantro in a large bowl. In a small bowl, whisk together the lime juice, olive oil, and sesame oil until combined. Toss the slaw with the vinaigrette and season to taste with salt and pepper. Taste, and feel free to add more lime juice, olive oil, or sesame oil if you like.
Garnish the salmon and the slaw with black sesame seeds. Serve with brown or black rice (if desired) and lime wedges.
