- 1/4 cup extra-virgin olive oil
- 2 tablespoons fresh lemon juice
- 1 4-5 pound butterflied leg of lamb, opened like a book

- Mix 1 cup yogurt, 1 teaspoon Tabil Spice Blend, and 1 minced garlic clove in a small bowl. Season to taste with salt and pepper. Cover and chill. Whisk remaining 1 cup yogurt, remaining 3 1/2 tablespoons Tabil Spice Blend, 4 minced garlic cloves, 1 tsp. salt, 1 teaspoon pepper, oil, and lemon juice in a large bowl. Add lamb; turn to coat.

- Prepare grill to medium-high heat. Season lamb with salt and pepper. Grill until meat is cooked to desired doneness, 10-15 minutes per side for medium-rare. Let rest 10 minutes.
