In a large mixing bowl, whisk together the flour and salt. Create a well in the center and add eggs. Gradually whisk in the milk until a smooth, lump-free batter forms. Stir in the melted butter. Allow the batter to rest for 30 minutes at room temperature to ensure tenderness.

Heat a non-stick skillet over medium heat and brush lightly with butter. Pour approximately 60 ml of batter into the pan, quickly swirling to coat the surface evenly. Cook for 1 to 2 minutes until the edges lift and the bottom is golden. Flip and cook for an additional 30 seconds. Transfer to a plate and repeat with the remaining batter to yield 8 crêpes.

On each crêpe, spread a thin layer of Dijon mustard if desired. Place one slice of ham and a generous sprinkle of shredded Gruyère in the center.

Fold the crêpe in half, then once again to form a triangle. Return the filled crêpe to the skillet over medium heat and cook for 1 to 2 minutes per side, or until the cheese has fully melted.

Serve immediately while hot, garnished with chopped parsley and freshly ground black pepper if desired.
