Bánh mì trứng - fried egg in a baguette - the Vietnamese breakfast sandwich. Here it is supplemented with asparagus and smoked salmon. As Leonardo Da Vinci is credited with saying: "Simplicity is the ultimate sophistication."
If the baguette has not recently come out of the oven, then give it a quick blast of heat over a grill or in the oven to return some crispness to the crust.
Cook the asparagus in a little butter for a minute or so.
Fry 2 eggs. More accurately, poach them in butter!
Cut the baguette horizontally
Layer the smoked salmon, the asparagus, and the eggs, and top with a pinch of salt and a good sprinkling of freshly ground black pepper.
