Spread the cream cheese: Generously spread cream cheese on each half of the bagel.
Add the smoked salmon: Lay the slices of smoked salmon evenly over the cream cheese.
Top with capers and onions: Sprinkle capers and place the red onion slices on top.
Garnish (optional): Add a few sprigs of fresh dill for extra flavor.
Serve and enjoy: Press the two halves together or leave them open-faced. Serve immediately for the freshest taste.
