Flat Irons and Skirt steaks cook super quick. You crank up the grill to 500 and flash each side for 3 minutes and let sit. In a pan cut up fresh portabella mushrooms, sweet onions add butter,salt,pepper, and the drippings from the steak, which is resting on a plate. Cook down until onions are translucent, add some Worcestershire sauce about three shakes and 1/2 cup of red wine. Cook for another few minutes and add 1 tablespoon of Corn Starch, Let it thicken
Slice steak in 45 degree angle cuts, make sure they are thin..Then just dig in.
