Steak with Balsamic Mushroom Sauce

Just prepared and ate it. Wow!!!  Enjoyed the prep, and despite always cooking steak, did a little research and learnt some useful tips. Such as, allow the steak to reach room temp before cooking. The Mushroom “sauce” was amazing, will definately be making again.
