Cook sausages in a skillet over medium heat; remove from the pan and let cool. Preheat oven to 400°F. Cut puff pastry sheets into 24 rectangles slightly larger than sausages. Cut 12 thin slices of cheese slightly smaller than the pieces of pastry. For each serving, place a slice of cheese in the center of a pastry rectangle and top with a sausage. Place another piece of pastry over the sausage. Fold down one corner and pinch the edges together. Place on a baking sheet and bake for 12-15 minutes, or until pastry is golden and puffed. Meanwhile, prepare the dipping sauce: Mix all ingredients together in a bowl. Serve the pigs with the dipping sauce. Makes 12 servings.
