In a small bowl, combine mayonnaise, ketchup and relish and set aside. To assemble pinwheel, spread 2 tablespoons of dressing on wrap, leaving a 1/4-inch border around the edge. Layer with turkey and pastrami. Starting at one end, roll tightly, like sushi, and cut into 4 equal sections. Repeat with remaining wraps, dressing and deli meat and serve with extra dressing and chopped salad.
