Preheat panini press (like The Griddler
) to high heat. Sprinkle both sides of chicken breasts with salt and pepper. Brush panini press with olive oil, add chicken breasts, and close panini press to grill on both sides at once. Grill for about 15 minutes or until cooked through, flipping once halfway through and rotating slightly to make nice diamond-shaped grill marks, if desired.
