Prepare the batter: In a mixing bowl, whisk together flour, eggs, milk, melted butter, and a pinch of salt until smooth. Let the batter rest for 15–30 minutes.
Cook the crêpes: Heat a non-stick skillet over medium heat. Lightly grease with butter. Pour a small amount of batter into the pan and swirl to coat evenly. Cook for 1–2 minutes per side, until lightly golden. Repeat with remaining batter.
Add the filling: Place a slice of ham and a generous handful of shredded cheese on one half of each crêpe. Fold the crêpe over the filling and cook for another minute until the cheese melts.
Serve: Garnish with fresh herbs if desired and serve immediately.
