Heat the oil, fry the mince in it until it is crumbly and brown. Add the diced onion, the diced carrot and the leek cut into thin rings. Steam everything for about 6 - 8 minutes in its own juice, then season with salt and pepper. Mix in the rice, pour in the broth and stir well. Cook for 20 minutes and then try to see if the rice is cooked enough. Sprinkle with chopped parsley and season with a pinch of butter.
The vegetable onions and carrots give the stew a slightly sweet taste that is particularly popular with children.
