Prep the cucumber: Wash and dry the cucumber.
Use a vegetable peeler to make a few light stripes down the sides if you like the look. Slice into thick rounds, about 1/2 inch each. Pat the tops dry with a paper towel so the spread sticks better.
Make the spread: In a small bowl, mix cream cheese, lemon juice, lemon zest, dill, capers, and garlic.
Add a pinch of salt and pepper. If it’s too thick, stir in a teaspoon of olive oil to loosen. Taste and adjust seasoning.
Prepare the salmon: If using smoked salmon, cut it into bite-size pieces.
If using cooked salmon, flake it gently with a fork. Aim for pieces that fit neatly on the cucumber rounds.
Assemble the bites: Add a small dollop (about 1 teaspoon) of the spread to each cucumber slice. Top with a piece of salmon.
Press lightly so it stays put but don’t squash the cucumber.
Season and garnish: Finish with a crack of black pepper. Sprinkle with everything bagel seasoning or a light dusting of smoked paprika if you want extra flavor and color.
Serve: Arrange on a platter with lemon wedges. A quick squeeze of lemon over the top right before serving makes everything pop.
