Peel and finely chop the onion. Peel and wash the potatoes. Clean and peel carrots. Cut both into pieces. Heat 2 tablespoons of oil in a pot and fry the onions in it.
Add potatoes and carrots and fry for about 5 minutes. Season with salt and pepper. Deglaze with broth and cook for about 15 minutes. In the meantime clean and wash the cauliflower and broccoli and divide into florets.
Add the cauliflower about 10 minutes, broccoli about 7 minutes before the end of the cooking time and cook along. Form small balls from the minced meat. Heat the rest of the oil in a pan and fry the balls for 5-6 minutes.
Add to the stew shortly before the end of the cooking time. Wash parsley, dab dry, pluck leaves from the stalk and chop finely. Sprinkle over the stew, season again and serve.
