Cook chickpeas in advance: Soak chickpeas overnight and cook them beforehand to save cooking time. Soak rice in water for 30 minutes before cooking.
Boil grains: In a deep pot, add water, rice, and chickpeas. Bring to a boil.
Add herbs and yogurt: Chop fresh herbs and add to the pot. Dilute yogurt with a little water and stir in. Season with salt and pepper. Cook for 30 minutes on low heat.
Prepare garlic-onion topping: Heat a small amount of oil in a pan, fry garlic and onion, add dry mint, and remove from heat quickly to avoid bitterness.
Serve: Pour the soup into serving bowls, garnish with fried garlic, onion, and fresh mint. Serve warm or slightly cooled.
