Balsamic Steaks

I received a bottle of "Newman's Own" organic balsamic vinegar for Christmas this year. I was looking for some recipes to try it with and came across this old newspaper clipping. I made the steak last night and it was really good! (Although the recipe calls for cooking on the stove, we chose to grill ours.)
