Heat the olive oil in a large pot over medium heat. When the oil shimmers, add the onion and cook 5 minutes until soft. Add the chickpeas and season with salt and pepper. Cook, stirring occasionally until he chickpeas begin to crisp, about 5 minutes. Add the garlic, turmeric, crushed red pepper, and lemon zest, cook until the garlic is fragrant, about 1 minute. Carefully remove 1 cup of chickpeas and reserve for topping, only if desired. To the chickpeas, add 3 cups broth, the lemon juice, and season with salt. Bring the mix to a boil over high heat, then reduce the heat to low. Stir in the spinach, cilantro, parsley, dill, and chives, and simmer 10-15 minutes, until the spinach is wilted and the stew is very fragrant. Taste, adjusting salt and pepper as needed. If you would like a thinner consistency, add the remaining 1 cup broth.To serve, divide the rice among bowls and ladle the stew overtop. Top with yogurt, the reserved chickpeas, and fresh mint.
