Cook the rice in boiling salted water at low heat for 15-20 minutes. In the meantime peel and quarter the onion. Clean and wash peppers and zucchini. Cut half into larger pieces. Dice the other half.
Wash the meat, dab dry and cut into pieces. Put meat, bell pepper, zucchini and onion alternately on skewers. Heat oil in a pan and fry the skewers in it for about 10 minutes, turning them occasionally. Season with salt and pepper. Remove from the pan and keep warm. Add remaining vegetables to the frying fat and fry for 2-3 minutes. Deglaze with stock and bring to the boil. Add rice and fold into the vegetables. Heat up again briefly and season with salt and pepper.
