Parboil the rice until partially cooked; drain and let cool slightly.
Combine the rice with ground meat, grated onion, chopped herbs, chickpea flour, egg, turmeric, cinnamon, and salt; knead well into a cohesive mixture.
Prepare the filling by frying onions until golden and mixing with raisins and prunes.
Shape portions of the rice-meat mixture around a spoonful of filling, forming smooth round balls.
Simmer the koofteh balls gently in a pot with oil and water, covered, until fully cooked through, about 45-60 minutes.
