01 - Place the turkey breast slices in a bowl or resealable bag. Pour over the pickle juice and add black peppercorns if using. Cover and refrigerate for at least 1 hour, or up to 4 hours, to brine.
02 - Drain the brined turkey and pat thoroughly dry with paper towels. In a small bowl, combine the mayonnaise, Dijon mustard, and chopped fresh dill (if using).
03 - Lay out the tortillas. Evenly spread the mayonnaise-mustard mixture over each tortilla, maintaining a 2 cm (1 inch) border. Layer lettuce, cheese, turkey slices, bacon, and tomato slices onto each tortilla. Season lightly with salt and freshly ground black pepper.
04 - Fold in the sides of each tortilla, then roll up tightly from the bottom to fully enclose the fillings. Slice each wrap in half diagonally and secure with toothpicks if desired. Serve immediately, or wrap tightly and chill for later enjoyment.
