makes: 8 servings 
Ingredients
4 pound tenderloin of beef
Salt and pepper to taste
2 sprigs rosemary, chopped
2 sprigs thyme, chopped
1 bunch chervil, chopped
1 1/2 cups Stonyfield Organic Low Fat Plain Yogurt
1/4 cup olive oil
Salt and pepper to taste
1 cup Gorgonzola, crumbled
Directions
Rub tenderloin with salt and freshly ground pepper, place in a roasting pan and set aside. In a medium-size mixing bowl, combine rosemary, thyme, chervil, yogurt, olive oil, salt and pepper. Pour half of the yogurt mixture over the tenderloin and refrigerate for 45 minutes (or up to 6 hours). Add Gorgonzola to the remaining yogurt mixture, cover and refrigerate.
Preheat oven to 350°F. Remove tenderloin from marinade. Heat a griddle or large skillet over medium-high and brown tenderloin on all sides. Place tenderloin in a clean roasting pan and bake in oven for 35 minutes or until internal temperature has reached 120°F. Let tenderloin rest for 15 minutes before carving. Top each serving with either cold or warm yogurt Gorgonzola Sauce.
To warm Gorgonzola sauce, place the yogurt Gorgonzola sauce in a medium-size sauce pan and gently warm the sauce over medium-low heat, stirring constantly until just warmed through. Serve immediately.
