01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.
02 - In a small saucepan, combine orange juice, honey, soy sauce, ginger, garlic, orange zest, sesame oil, pepper, and salt. Bring to a simmer over medium heat and cook for 4-5 minutes, stirring occasionally, until slightly thickened. Remove from heat.
03 - Place salmon fillets on prepared baking sheet. Brush each fillet generously with the orange-ginger glaze, reserving some for basting during cooking.
04 - Bake for 10-12 minutes until fish flakes easily with a fork. Halfway through baking, brush fillets with additional glaze.
05 - Remove from oven and transfer to serving plates. Drizzle with remaining glaze. Garnish with green onions, sesame seeds, and orange slices if desired. Serve immediately.
