Blue Cheese Tenderloin with Merlot Sauce

Steak. I mean, come on people. If you have going to eat at all it might as well be steak. And if you are going to have steak, you might as well have it covered in a bleu cheese sauce. mmmm...and some carmelized onions as well. Steak alone however does not make a meal, so the appropriate side dish is mashed potatoes, of course.
