01 - Pat the salmon fillets dry with paper towels. Season both sides evenly with salt and pepper.
02 - Heat 1 tablespoon olive oil in a large non-stick skillet over medium-high heat.
03 - Place salmon fillets skin-side down in the hot skillet. Press gently with a spatula to prevent curling. Cook for 5 to 6 minutes until the skin crisps and the flesh becomes mostly opaque.
04 - Turn the fillets over and cook for 1 to 2 minutes until just cooked through. Remove from heat and allow to rest briefly.
05 - In a large bowl, whisk together lemon juice, extra virgin olive oil, Dijon mustard, honey, salt, and pepper until emulsified.
06 - Add the thinly sliced fennel, julienned apple, sliced red onion, and chopped dill to the dressing. Toss thoroughly to coat all components evenly.
07 - Divide the fennel slaw evenly among four plates. Top each portion with a salmon fillet, skin-side up.
