01 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
02 - Arrange salmon fillets on the prepared tray. Drizzle with olive oil, season evenly with sea salt and black pepper, and top with lemon slices.
03 - Bake for 15 to 18 minutes until the fish is opaque and flakes easily. Allow to cool slightly before flaking into large chunks.
04 - Combine the softened cream cheese, chopped dill, chives, and lemon zest in a small bowl. Mix until smooth and homogeneous.
05 - Lightly toast the cut sides of the bagels until golden brown.
06 - Spread a generous layer of the herbed cream cheese onto each bagel half. Top with the flaked baked salmon.
07 - Layer the red onion, cucumber, and tomato slices over the salmon. Finish with capers and fresh dill sprigs.
08 - Serve immediately while the bagels are still warm.
