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°. 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°. 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.
