Valentine's day special: Roasted rack of lamb

Here is the recipe!

Ingredients:
Rack of lamb (frenched)
Half Onion
Two tomatoes
1 tablespoon rosemary
1 tablespoon oregano
1 tablespoon thyme
1 teaspoon cumin
half cup olive oil
Salt
Pepper

Directions:
1. Stir the olive oil and herbs and rub the herb mixture over each side of the rack. Set aside.
2. Puree tomatoes and onions in a blender.
3. Pour the marinade over the rack of lamb, cover and refrigerated it at least 3 hours and up to overnight.
4. Remove the lamb from the refrigerator and allow it to sit for 30 minutes. (A piece of meat at room temperature will roast more evenly.) Preheat the oven to 160C (325F).
5. Sprinkle both side of the lamb with salt and pepper. Heat 2 tablespoon of olive oil in a pan and sear the lamb for 1 to 2 minutes on all sides.
6. Roast the lamb with the marinade in the preheated oven for 30 to 45 minutes.
7. Remove the lamb from the oven, place a foil tent loosely over it, let it rest for about 15 minutes, and serve it with the marinade.
