Lay out smoked salmon with capers, red onion, and cream cheese for a low carb dinner that requires zero cooking and maximum sophistication.
Arrange the smoked salmon slices on a large chilled plate in even layers to maintain moisture without overlap.
Soften cream cheese at room temperature for 10 minutes, then spoon into small dollops alongside the salmon for easy spreading.
Finely slice the red onion into thin rings or half-moons for a crisp, mild flavor, and scatter over the plate.
Rinse capers to reduce excess salt, then sprinkle evenly over the salmon for balanced brininess.
Add lemon wedges and fresh dill sprigs; finish with a light twist of black pepper just before serving to brighten the flavors.
