Whisk miso, soy sauce, honey, rice vinegar, sesame oil, garlic and ginger until smooth. Adjust balance if needed.
Pat salmon dry, season lightly, and brush half the glaze over each fillet. Let rest 5–10 minutes at room temperature.
Cook rice according to package directions. Keep warm until ready to assemble.
Oven: Roast at 425°F for 8–12 minutes, brush with remaining glaze and broil 1–2 minutes to caramelize. Skillet: Sear over medium-high heat 3–4 minutes per side, brushing glaze in the final minutes.
Divide rice among bowls, top with salmon, arrange cucumber, carrot and pickles, and finish with green onions and sesame seeds.
Notes
Glaze stores in the fridge for up to 4 days.
Serve on greens instead of rice for a lower-carb bowl.
