Heat a grill pan to medium heat.
Season the steak liberally with salt and pepper. Cook for 6 minutes on each side for medium rare. *Cook's Note: If you prefer medium, cook for 8 to 10 minutes per side.
Remove from heat, cover with foil to make a tent. Rest for 5 minutes before slicing steak. Cut into 1/8-inch thick slices. Transfer to a platter and ladle on Gorgonzola Cream Sauce.
