Caramelized onion tart

Directions

• Heat oven to 400 degrees F. Mix Gruy?re, cream cheese, mustard, oregano, and pepper in a small bowl and set aside. Melt butter in a large skillet, add onions, and cook, stirring occasionally, over medium-low heat until dark brown and caramelized ? about 1 hour. Stir in the thyme and set aside.
• With a sharp knife, cut the puff pastry dough into 8 equal-sized pieces. Roll each piece out to 8- by 6-inch rectangle. Spread about 1/4 cup of the cheese mixture on the dough, leaving a 1/2-inch border all the way around.
• Top with 1/4 cup of the caramelized onions and 1 tablespoon of the olives.
