Italian Stuffed London Broil

"Here is a fantastic recipe using flank steak. The flank steak pinwheels or Italian Stuffed London Broil produces an amazingly tender stuffed steak. Inside the roll is thinly sliced prosciutto and ooey gooey provolone cheese. I know you are going to love it! The flavors of this Italian Stuffed London Broil are so complex. First, the marinade starts to add flavor to the beef. Then the ingredients for the stuffing are added to the dish. Finally, the grill works its magic, searing the meat with a nice char on the outside, then slowly cooking it to mouthwatering perfection!"
