Cut the salmon fillets into 1-inch cubes. In a bowl, toss them with olive oil, garlic powder, onion powder, smoked paprika, cayenne (if using), salt, and black pepper until evenly coated.

Heat a large skillet over medium-high heat. Cook the seasoned salmon cubes for 2-3 minutes per side until golden brown and just cooked through.

While the salmon cooks, whisk together mayonnaise, Thai sweet chili sauce, sriracha, honey, and lime juice in a small bowl until smooth and well combined.

Once the salmon is cooked, drizzle with the bang bang sauce or toss gently to coat. Serve immediately while hot.
