01 - Pat the salmon fillets completely dry with paper towels. Lightly score the skin 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.
03 - Place salmon fillets skin-side down in the hot pan. Press firmly with a fish spatula for 30 seconds to prevent curling and ensure even skin contact.
04 - Cook skin-side down for 4-5 minutes without disturbing, until skin is golden brown and crispy and salmon flesh is mostly opaque up the sides.
05 - Carefully flip fillets and cook 1-2 minutes longer, until just cooked through with a slight translucency at the center. Remove from heat and rest for 2 minutes.
06 - In a large bowl, combine 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 - Arrange fresh herb salad on plates and top with rested crispy skin salmon fillets, skin-side up for presentation.
