Whole Flank Steak - dry rubbed with A1 Origional Bold dry rub mix - apply liberally
place in zip lock bag
1/3 bottle teriyaki
light splash of soy sauce (maybe 3-5 tablespoons)
dash of worschester
burp out all the air
marinade 3 days - if you can wait that long - minimum overnight

cook to desired temp - i like to take my beef off the heat at an internal temp of between 120 and 125
slice diagonally across the grain.
sauteed baby bella's w/ onions and garlic
italian seasoning mix of dried herbs to taste
salt and pepper to taste
enough olive oil to sautee
mushroom and onion pan was deglazed with Founders Dirty Bastard to finish after caramelizing - but only because its what i was sipping while cooking

you could also deglaze with something like a nice Demi-Glace if you wanted to make it more of a sauce.
This pairs exceptionally well with fresh sweet corn (when in season)
Pro Tip: Cooking Beef by the Numbers
Want to impress company by cooking a perfect steak, etc? then use a meat thermometer to measure the internal temp of the thickest spot of the cut of beef. the following temp scale will produce a nearly perfect temping every time -- unless your thermometer is off or the person requesting is incorrect as to what their assumption of "medium" is of course hehe!
110*F - Rare
120*F - Medium Rare
130*F - Medium
140*F - Medium Well
150*F - Well Done
160+ - blasphemy :x
