01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Place salmon fillets on the prepared baking sheet. Drizzle with olive oil and season thoroughly with salt, black pepper, garlic powder, and smoked paprika. Arrange lemon slices on top of each fillet.
03 - Bake for 12-15 minutes until the salmon is opaque throughout and flakes easily when tested with a fork. Remove from oven and let rest for a few minutes.
04 - While salmon bakes, arrange mixed salad greens, cherry tomatoes, cucumber slices, red onion, avocado, and capers evenly on two serving plates.
05 - In a small bowl, whisk together extra-virgin olive oil, fresh lemon juice, Dijon mustard, chopped fresh dill, and honey until fully emulsified. Season with salt and pepper to taste.
06 - Flake the warm salmon into large chunks and distribute over the prepared salads. Drizzle with vinaigrette and serve immediately with extra lemon wedges if desired.
