Look for packaged sliced smoked salmon. Conveniently, each slice should be one ounce.
Combine first 3 ingredients; stir until smooth. Spread about 1 tablespoon cheese mixture evenly over each crepe. Sprinkle each with about 1 teaspoon chives; top each with 1 salmon slice. Roll up each crepe, jelly-roll fashion. Cover and chill 1 hour. Cut each roll crosswise into 10 pinwheels.
