01 - In a mixing bowl, whisk together flour and salt. Add eggs and half of the milk, whisking until smooth. Gradually incorporate the remaining milk and melted butter, whisking until the batter is thin and free of lumps. Let the batter rest for 10 minutes.
02 - Preheat a 9-inch non-stick skillet over medium heat and brush lightly with butter.
03 - Pour approximately 1/4 cup of batter into the skillet, swirling to create a thin, even layer. Cook for 1 to 2 minutes until edges lift and the bottom turns golden.
04 - Flip the crepe carefully and cook for an additional 30 seconds.
05 - Sprinkle one quarter of the cheese mixture over the crepe, season with black pepper and optional herbs. Fold the crepe in half, then in quarters to enclose the filling.
06 - Cook the folded crepe for 1 more minute until the cheese is melted. Transfer to a plate and keep warm.
07 - Repeat the cooking process with remaining batter and filling. Serve immediately, garnished with extra herbs if desired.
