In a small bowl, whisk together orange juice, orange zest, soy sauce, honey, rice vinegar, sesame oil, ginger, and garlic.
In a separate small bowl, mix cornstarch and water to create a slurry and set aside.
Pat salmon fillets dry with paper towels and season lightly with salt and pepper.
Heat vegetable oil in a large non-stick skillet over medium-high heat.
Place salmon fillets skin-side up in the skillet and sear for 4-5 minutes until golden brown.
Flip the fillets and cook for an additional 3 minutes.
Pour the sauce mixture into the skillet around the salmon.
Whisk the cornstarch slurry into the sauce and simmer for 2 minutes until the glaze thickens and coats the salmon.
Remove from heat and garnish with sliced green onions and toasted sesame seeds.
