01 - Pat the salmon fillets dry with paper towels. Score the skin lightly with a sharp knife in a crosshatch pattern. Season both sides generously with sea salt and black pepper.
02 - Heat 1 tbsp olive oil in a nonstick skillet over medium-high heat until shimmering but not smoking.
03 - Place the salmon fillets skin-side down in the hot pan. Press gently with a spatula for the first 30 seconds to prevent curling and ensure even skin contact.
04 - Cook skin-side down for 4-5 minutes, until the skin is golden brown and crispy, and the salmon flesh is mostly opaque up the sides.
05 - Flip the fillets and cook for 1-2 more minutes, or until just cooked through. The center should remain slightly translucent for medium. Remove from heat and let rest for 2 minutes.
06 - In a large bowl, combine the mixed greens, red onion, dill, parsley, capers, and lemon zest. Drizzle with extra-virgin olive oil and lemon juice. Season with salt and pepper. Toss gently to coat evenly.
07 - Divide the herb salad between two plates. Top each salad with a crispy skin salmon fillet, skin-side up. Serve immediately while the salmon is still warm.
