Whisk the soy sauce, honey, sriracha, sesame oil, garlic, and lime juice in a small, shallow dish. Place the salmon fillets in the marinade and toss to coat on all sides. Leave to marinate in the fridge for 30 minutes.
Preheat the oven to 400°F/200°C/Gas 6 and line a rimmed baking sheet with a piece of parchment paper.
Arrange the salmon fillets onto the prepared baking sheet and drizzle with any leftover marinade. Roast for 14-16 minutes until lightly browned, but still flakey in the middle.
Sprinkle with sesame seeds and fresh scallions. Serve with hot cooked rice, and a side salad if desired. Enjoy!
