Lay a piece of plastic wrap on the counter. Sprinkle plastic wrap with sesame seeds. Place smoked salmon over the sesame seeds, overlapping the slices to form a 10 x 6" rectangle
Spread whipped cream cheese over the top of the smoked salmon. Sprinkle with chives and lemon zest.
Place sliced avocado and cucumbers along the long edge of the salmon, then use the plastic wrap to help roll the salmon over itself.
Toss roll up in the freezer for 10 minutes before slicing. Slice into 12 pieces, and enjoy!
