Method:
Bring 1/2 cup broth to a simmer in a large pot or high-sided skillet over medium-high heat. Add onion and garlic and cook 5 minutes or until tender and translucent. Add lamb, 1 1/2 teaspoons dill, oregano and cinnamon and cook 6 to 8 minutes or until browned, stirring to break up lamb. Stir in lentils and remaining 2 1/2 cups broth. Bring to a boil, then reduce heat to low. Cover and simmer, stirring occasionally until lentils are tender, about 45 minutes.
Meanwhile, in a separate medium saucepan, bring rice and 2 cups water to a boil. Reduce heat to low, cover and simmer until liquid is completely absorbed and rice is just tender, about 40 minutes.
In a small bowl, combine tahini and lemon juice, then stir in cucumber and tomato. Spoon lamb and lentils over rice and top with cucumber mixture. Sprinkle with remaining dill and serve.
