Preheat your oven to 400°F (200°C).
In a small bowl, whisk together the mayonnaise, sweet chili sauce, sriracha, lime juice, garlic powder, onion powder, salt, and pepper until smooth. Set aside.
Pat the salmon fillets dry with paper towels and season both sides with salt and pepper.
In an oven-safe skillet, heat the olive oil over medium-high heat. Once hot, add the salmon fillets skin-side down and sear for about 3-4 minutes until the skin is crispy.
Carefully flip the salmon fillets and spoon the bang bang sauce over the top of each fillet.
Transfer the skillet to the preheated oven and bake for 8-10 minutes, or until the salmon is cooked through and flakes easily with a fork.
Remove from the oven and let it rest for a couple of minutes. Garnish with sliced green onions and serve with lime wedges.
