Preheat oven to 400°F.
Unroll danish pastry dough out on a floured surface. Using a knife, cut 1/4-1/2" tabs along both long sides. Be sure and check out this Apple Braid recipe for a great visual look at an easy method to make the cuts for the braid.
Spread the Dijon Mustard in the center of the dough.
Layer the ham slices up on top of the Dijon Mustard.
Layer the Swiss Slices next.
Braid the bread dough.
Cut the asparagus to about 2" including the head.
Slide them in between the different braided spots like you see in the photo.
In a small bowl, beat the egg white and water together. Brush across the top of the bread. Sprinkle sea salt lightly over the top and on the asparagus, if desired.
Bake at 400°F for 15-20 minutes.
