Fry the pancetta slices in a large skillet over high heat until crispy. Remove from the pan and set aside.
In a large bowl combine the chicken, radicchio, mayonnaise, curry powder, lime juice, honey, and ginger. Stir to combine.
Slice the rolls in half. Spoon the chicken mixture onto the bottom halves of the rolls. Cover with the crispy pancetta and the top of the rolls. Serve.
