01 - Pat the salmon fillets completely dry with paper towels. Score the skin lightly in a crosshatch pattern with a sharp knife, being careful not to cut into the flesh. Season both sides generously with sea salt and freshly ground black pepper.
02 - Heat 1 tbsp olive oil in a nonstick skillet over medium-high heat until shimmering but not smoking. The pan should be hot enough to sizzle immediately when the salmon touches it.
03 - Place the salmon fillets skin-side down in the hot pan. Press gently with a spatula for the first 30 seconds to prevent the skin from curling and ensure even contact with the pan surface.
04 - Cook skin-side down for 4-5 minutes without disturbing the fish. The skin should become golden brown and audibly crispy, and the salmon flesh should turn mostly opaque up the sides.
05 - Carefully flip the fillets and cook for 1-2 more minutes, or until just cooked through. The center should remain slightly translucent for optimal moisture. Remove from heat and let rest for 2 minutes.
06 - In a large bowl, combine the mixed greens, thinly sliced red onion, chopped dill, parsley, capers, and lemon zest. Drizzle with extra-virgin olive oil and fresh lemon juice. Season with salt and pepper, then toss gently to coat evenly.
07 - Divide the herb salad between two plates. Top each salad with a crispy skin salmon fillet, placing it skin-side up to maintain crispness. Serve immediately while the salmon is still warm.
