1 sheet frozen puff pastry, thawed
With a sharp knife, score (cut, but not all the way through) about a half inch in from the edges of the rectangle, creating a crust, all the way around the rectangle. Prick the inside of the rectangle all over with a fork (see photos if you're not sure how to do this).

Notes
Asparagus: Pencil-thin spears work best for this tart because they cook quickly, are more attractive, and can be sliced more easily. However, if thin spears aren't available, thicker spears are okay, too. I find that they work best if you slice the stalks into 1-inch pieces. The smaller pieces will get tender more quickly and the tart will be easier to slice.
Mustard: If you're not a fan of Dijon, try stone-ground mustard or whole grain mustard. Honey mustard or a Bavarian-style mustard would add a sweeter note.
Cheese: If you prefer, a different kind of cheese can be substituted. Try Swiss cheese, baby Swiss, shredded Parmesan or another cheese you like. (White cheese is more attractive for this tart.) You can use more than 1 ½ cups of cheese, or a combination of cheese, if you like. I sometimes use sharp provolone on the bottom, and sprinkle shredded Parmesan over the asparagus. Another option is a spreadable cheese, like Boursin.
