Pan Seared Flat Iron Steak with Onions and Blue Cheese

We met friends Sunday morning in a small little bistro in the mountains for breakfast.  The day was gorgeous and the trees were stunning in their Fall finery of yellows and reds.  I really didn't have a plan for dinner.  On the way home we stopped at the butcher shop and simply chose what jumped out at us.  They had some nice Flat Iron Steak on sale...ta da, decision was made.  I saw Ree Drummond make rib eye steaks with an onion blue cheese sauce awhile back on television.  I took the idea and tweaked a little to make it fit what I had on hand and not take away from the beauty of the meat.  We both decided this sauce would be great on old shoes!  Delicious and easy.  Be patient!  The key to sweet, caramelized onions is patience.  Use as much blue cheese as you like to suit your taste.  I am also thinking of using these flavors to come up with a hot dip at some point.
