In a medium bowl, combine egg, milk and flour. Beat until well mixed.
Spray an unheated 6-inch skillet with nonstick cooking spray. Preheat skillet over medium heat. Remove from heat and add 2 tablespoons batter. Lift and tilt skillet to spread batter. Return the skillet to heat. Cook 30 to 60 seconds, or until browned on one side only. Remove from pan.
Repeat with remaining batter to make 15 crepes. Lightly brush skillet with shortening between cooking, as needed.
