1. Whisk all kabob ingredients, minus the meat, in a deep bowl. Add lamb, stir to coat, cover and marinate in refrigerator 2 hours.
2. Preheat grill to high. Thread lamb onto skewers. Cook kabobs 6 to 8 minutes, turning halfway, until cooked through.
3. For the salad, bring chickpeas, bay leaf, onion and 1 cup cold water to boil in a small pot. Reduce to a simmer and cook 5 minutes. Drain chickpeas, discarding bay leaf and onion, and coarsely mash with a fork. Stir in remaining ingredients. Serve kabobs over salad, drizzled with extra olive oil if desired.
