Remove the puff pastry from the freezer or refrigerator and let it rest until it's room temperature.

Preheat the oven to 400 degrees F.

Wash the asparagus in a colander and trim the ends off the asparagus.

In a large skillet or pan, bring the water to a boil and cook the asparagus until it turns a bright green color and is tender (approximately 5 minutes). Do not overcook it.

On a parchment-lined baking sheet, roll out the puff pastry and poke the surface several times with a fork. Bake it in the oven on the middle rack for 10 minutes or until it becomes golden brown.

While the puff pastry is in the oven, whisk together the egg yolks and milk in a medium-sized bowl.

Remove the puff pastry from the oven and place the cheese on top of the pastry leaving about an inch on all sides. Sprinkle or brush the olive oil on top of the cheese and then arrange the asparagus side by side on top. With a brush, coat the asparagus with the egg mixture. Sprinkle with salt and pepper.

Put the pan back into the oven and bake for 15-20 minutes or until the pastry puffs up and the cheese has melted. Remove from the oven and let cool for 5 minutes before serving.
