Thaw puff pastry according to package directions. Preheat oven to 375 degree F. Unfold pastry. Using a 2-inch fluted or round cutter, cut pastry into circles. Do not reroll pastry scraps. Place pastry rounds on an ungreased baking sheet. Bake about 15 minutes or until puffed and lightly browned. Remove to a wire rack and let cool.
Split pastry rounds. Evenly spread 1/2 teaspoon of the Tomato Tapenade over the bottom half of each round. Top with some of the shrimp. Sprinkle with cheese. Replace tops. Return filled pastries to baking sheet. Bake about 5 minutes more or until cheese is just melted. Serve warm. If desired, garnish each serving with a grape tomato half and a shrimp. Makes 20 crostini.
Finely chop oil-packed dried tomatoes. In a small bowl, combine the chopped tomatoes, oil from the tomatoes, capers, garlic, anchovy paste, and ground black pepper. Mix well. Makes 1/3 cup.
