> 1 (1/2 oz) pkg Nature's Promise® Organic Roasting Blend (Rosemary, Thyme and Parsley)
> 4 cloves garlic, minced
> 1 (3- 4 lb) top sirloin
> 1 tbsp olive oil
> 1 cup fat-free sour cream
> 1/2 cup nonfat Greek yogurt
> 1/3 cup prepared horseradish
> 1 tsp lemon juice
> 3/4 tsp dry mustard
> 2 tbsp chopped chives, plus more to garnish


Preheat oven to 425°F with an oven rack in middle position. From the herb blend, remove thyme and rosemary leaves. Finely chop enough to total ½ tbsp of each. Reserve all remaining herbs for later. In a small bowl, combine the garlic, thyme, rosemary, salt, and pepper. Rub the beef with the oil and then herb mixture. Add beef to a roasting pan.
Roast beef 20 min. Decrease oven temperature to 250°F and continue roasting 2 hours longer, until a meat thermometer registers 135°F for medium-rare. Transfer to a carving board and cover loosely with foil. Let rest at least 10 min.
Meanwhile, in a small bowl, stir together the sour cream, yogurt, horseradish, lemon juice, and dry mustard. Finely chop reserved herb leaves. Stir herbs and chives into sauce and season with salt and pepper. Garnish sauce with more chives. Thinly slice beef and serve with horseradish-herb sauce.


For more flavor, season the beef 1 day before roasting. Wrap tightly and refrigerate until ready to roast.
