Sirloin with Sour Cream Sauce Recipe

My in-laws raise beef for all their children, so I'm always looking for new ways to cook steak. This is an absolute favorite. It's so easy to fix, and the result is a tender steak smothered in a creamy onion and mushroom sauce. The aroma alone makes my husband's mouth water!
