01 - Combine smoked paprika, garlic powder, onion powder, dried thyme, dried oregano, cayenne pepper, black pepper, and salt in a small bowl. Mix thoroughly to ensure even distribution.
02 - Pat salmon fillets completely dry using paper towels. Rub olive oil over each fillet, then press the spice mixture onto all surfaces, ensuring an even coating.
03 - Place a large cast iron skillet over medium-high heat and allow it to become thoroughly hot. Add a small splash of oil if the skillet is not well-seasoned.
04 - Arrange salmon fillets in the hot skillet without overcrowding. Sear for 3-4 minutes per side until a dark, aromatic crust forms and the fish reaches desired doneness while remaining moist in the center.
05 - While salmon cooks, combine diced mango, avocado, red bell pepper, red onion, and cilantro in a mixing bowl. Drizzle with lime juice and season with salt and pepper. Gently fold to incorporate without mashing the avocado.
06 - Transfer salmon to serving plates. Top each fillet generously with mango avocado salsa. Accompany with lime wedges and serve alongside cooked rice or mixed greens if desired.
