01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with nonstick spray.
02 - Pat salmon fillets dry and place on prepared baking sheet. Drizzle evenly with olive oil, then season with kosher salt, black pepper, and smoked paprika.
03 - Bake for 15 to 18 minutes until salmon flakes easily with a fork and is just opaque in the center.
04 - While salmon bakes, combine diced tomatoes, red onion, jalapeño, cilantro, lime juice, and sea salt in a medium bowl. Mix well and allow to rest at room temperature for flavors to develop.
05 - Transfer baked salmon fillets to serving plates.
06 - Top each salmon fillet with generous portions of salsa fresca. Garnish with lime wedges and additional cilantro. Serve immediately.
