Heat up an oven proof skillet (cast iron works great for this) to medium-high heat. When the pan is nice and hot, add a little oil to the pan and brown all sides of the meat roll. Remove the meat from the heat and transfer to a cutting board, but keep the pan hot. Slice into pieces about 1 inch thick. Try to keep the butcher twine around each slice. Place back into the skillet and place in oven for 5 mins. Remove from oven when the cheese is all melted and the steaks are nice and browned.
