Arrange two medium sage leaves, 1 slice prosciutto and 1/2 slice mozzarella cheese on each piece.
Roll each breast in a jelly-roll fashion beginning with the long side. Secure with toothpicks.
Heat the 12" Large Skillet over medium heat until water droplets bead across the surface of the pan, about 3 minutes.
Place chicken roll-ups in the hot dry pan and brown evenly all over, about 10 to 12 minutes. The chicken will stick initially and is ready to turn once it comes away from the surface with no resistance.
Transfer roll-ups to a cutting board. Discard toothpicks and slice into 1-inch pieces. Arrange on a serving platter and serve immediately.
