Spread the patties with cheese, cover with smoked salmon and sprinkle with chopped chives. Roll up the patties, tightening them a little. Wrap them individually tightly in cling film, refrigerate for 1 hour.
Cut the salmon steaks into cubes, sprinkle with a dash of lemon and roll them in the sesame seeds.
Unwrap the patties and cut them into 1 cm thick slices at the last moment and thread them by 3 on spikes (or alone).
Serve the salmon cubes on a small plate with a small cup of soy sauce.
Serve the two bites on a small platter.
