3 cups grated Gruyere cheese, about 10 oz

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 an 8x6 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 T of the olives.
