05 - Lightly toast the bagel halves to your preference.
06 - Spread each toasted bagel half generously with the herbed cream cheese, layer with flaked salmon, then top with red onion, cucumber, tomato slices, capers, and garnish with fresh dill sprigs.
07 - Serve immediately while the bagels remain warm.
