Cut the cucumber into slices (1/2 cm). Cut each slice of smoked salmon in half lengthwise (smaller than your cucumber slice).
Spread 1tsp of Boursin™ cheese on each salmon strip and roll it up.
Top each cucumber slice with a salmon roll. Insert a wooden stick down the center to keep everything together. Garnish with finely chopped fresh dill and paprika. Serve at once or keep refrigerated until needed.
