Melt the butter in a saucepan.
Stir in the flour and sauté briefly (do not brown!).
Gradually stir in the milk, stirring well to avoid lumps.
Bring to a boil, then stir in the cheese until melted.
Season with salt, pepper, and nutmeg.
✅ Tip for extra flavor:
Bake the doner meat briefly in the cheese sauce—this adds an extra special touch.
