1 For the lamb koftas: Soak the bread in a little lukewarm water. Squueze the bread dry and place in a bowl with minced lamb, egg, cilantro, chopped garlic and curry powder. If necessary add bread crumbs so that the mixture is easy to shape. Season with salt and pepper. Heat the oil in a skillet, shape the lamb mixture into patties and saute 3 minutes per side.

Heat 3 tablespoons olive oil in a pan and saute the peppers over medium heat, stirring occasionally until tender, 5-6 minutes. Stir in the pine nuts and cook briefly. Add the couscous and herbs, and saute, stirring for 2-3 minutes. Season with salt and pepper. Stir in the lemon juice and serve with the koftas and the yogurt sauce.
