Starting with smoked salmon, this bagel sandwich is layered with tasty ingredients—flavored cream cheese, capers, and purple onion. It's a quick fix for a brown-bag lunch.
Split bagel in half horizontally. Spread cut sides with cream cheese. Over cheese on 1 bagel half, layer cucumber, smoked salmon, red onion, and capers. Set remaining bagel half, cream cheese side down, over filling.
