01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with oil.
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 to 5 minutes, stirring occasionally, until slightly thickened. Remove from heat.
03 - Place salmon fillets on prepared baking sheet. Brush each fillet generously with orange-ginger glaze, reserving some for basting during cooking.
04 - Bake for 10 to 12 minutes until fish flakes easily with a fork. Brush with additional glaze halfway through baking time.
05 - Remove from oven and transfer salmon to serving plates. Drizzle with remaining glaze and garnish with green onions, sesame seeds, and orange slices. Serve immediately.
