Asparagus Gruyere Tart

From Everyday Food. This is very simple and works great as an appetizer. I have substituted swiss with good results.

• Ready In: 50 mins
• Serves: 4

Ingredients

•  flour, for rolling out pastry
• 1  sheet frozen puff pastry
• 5 1⁄2 ounces gruyere cheese, shredded (2 cups) or 5 1⁄2 ounces swiss cheese
•  thick asparagus, trimmed
• 1  tablespoon olive oil
•  salt and black pepper

Directions

1. Preheat oven to 400°. Roll the pastry into a 16-by-10 inch rectangle and place on a parchment-lined baking sheet.
2. Lightly score the dough with a knife 1-inch from the edges to form a rectangular outer edge. With a fork, pierce the dough inside the edge at half-inch intervals. Bake until golden, about 15 minutes.
3. Remove the pastry from the oven to scatter the cheese on top. Alternate the asparagus tip to end in a single layer on the cheese.
4. Brush with oil and season to taste. Bake until asparagus is tender, which will take about 20 to 25 minutes.
