A different look at steak

Cook the steak however you wish. High heat grilling is my favorite.
Salt and fresh pepper is all you need.
What is the best side ?
A superb full bodied red !
(2 bottles are better than 1)

Thanks guys, I did flank steak w the chimichurri with asparagus on the side. It was a hit.

Weber has an amazing bourbon marinade.

Au poivre. Or smothered in caramelized onions mushrooms and bleu cheese.

And I also vote for chimichurri. Which is also excellent on grilled halibut.
For side..maybe skip the potato and go with baked polenta fries.
and a side salad.

Chimichurri is an excellent idea. This is my go to:

Amanda's Sugar Steak with Bourbon is easy and very good: http://food52.com/recipes/10252-sugar-steak-with-bourbon
I've done it with flank and also flat iron steak, both worked well.

It's nothing revolutionary, but a good, spicy chimichurri is my idea of the perfect accompaniment for steak. Use tons of parsley, as much fresh chile as you want (serrano or jalapeno are our favorites, but you could use pretty much any hot chile), plenty of garlic, oregano, smoked paprika, red wine vinegar, olive oil, and salt. In Argentina, this is used as both a marinade and a sauce, and it really compliments the rich, deep flavors of grilled red meat.
