Roasted beef tenderloin with spiced blue cheese sauce

Tender, perfectly cooked beef topped with a creamy sauce is an ideal dish for any festive holiday celebration. The beef sirloin is first coated in Dijon mustard before roasting for an extra layer of flavor and is ready to go in just 35 minutes. Steamed green beans are tossed with sour cream, mayonnaise, horseradish, blue cheese, fresh lemon juice, and Worcestershire sauce and make for a wonderful, colorful, crunchy side for the beef. This satisfying, savory sauce goes well with chicken, pork, and fish as well. You'll find yourself making it over and over again and using it in a variety of ways.
