Undo croissant dough on an oven safe plate. Garnish with drained asparagus. It's imporant to well drain asparagus if you don't want your croissant to be soggy. Spread with cheese, up to taste. Salt and pepper.
Close the dough to form a croissant. Be sure that the dough is well closed or cheese will flow out. Cook until croissant browns, so about tens of minutes.
Chef’s note
Note : Serve hot. These asparagus croissant melt in your mouth.
