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. Generously season both sides with sea salt and freshly ground black pepper.
02 - Heat 1 tablespoon 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 fish spatula for the first 30 seconds to prevent the skin from curling. Maintain even contact with the pan.
04 - Cook skin-side down for 4-5 minutes without disturbing, until the skin is deeply golden and crispy, and the salmon flesh is 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. Remove from heat and let rest for 2 minutes.
06 - In a large mixing bowl, combine the mixed greens, red onion, dill, parsley, capers, and lemon zest. Drizzle with extra-virgin olive oil and fresh lemon juice. Season with salt and pepper. Toss gently to coat evenly.
07 - Divide the herb salad between two plates. Top each serving with a crispy skin salmon fillet, placing it skin-side up to maintain crispiness. Serve immediately.
