Preheat your oven to 375°F (190°C).
Line a baking sheet with parchment paper and place the salmon skin-side down.
Mix the miso paste, soy sauce, honey, rice vinegar, and sesame oil in a small bowl. Brush the glaze generously onto the salmon fillets.
Bake the salmon for about 12-15 minutes, or until the internal temperature reaches 125°F (52°C).
Meanwhile, cook the rice and prepare the greens, slicing the avocado and cucumber.
Assemble the bowls by placing a base of rice, followed by kale, arugula, and the baked salmon.
Top with avocado slices, cucumber, crispy shallots, and sesame seeds.
Drizzle the remaining miso glaze over the top and serve immediately.
