To prepare rice: Combine water, rice, raisins, olive oil, onion powder (or garlic powder), turmeric, cinnamon, pepper and ⅛ teaspoon salt in a small saucepan. Bring to a boil. Cover, reduce heat to maintain a gentle simmer and cook until the liquid is absorbed, 35 to 40 minutes. Remove from heat and let stand, covered, for 10 minutes.
Meanwhile, to prepare vegetables & chickpeas: Heat coconut oil (or ghee) in a medium skillet over medium heat. Add chickpeas and cook, stirring, until crispy, 3 to 5 minutes. Stir in garam masala (or curry powder) and cook until fragrant, about 1 minute. Add roasted root vegetables, sugar (or honey), salt and pepper; cook, stirring often, until heated through, 2 to 4 minutes. Stir in lemon juice.
Serve the vegetable mixture over the rice, topped with yogurt (or tahini). Garnish with herbs, if desired.
