Peel and finely dice the onions and garlic. Heat the oil in a pot. Fry half of the onions and garlic in it. Stir-fry the rice until transparent. Add stock and chunky tomatoes.
Cover and cook for about 25 minutes. Stir from time to time. In the meantime, knead remaining onions, garlic, egg and minced meat. Season with salt, pepper, marjoram and paprika. Form 12 small dumplings from the minced meat.
Clean, wash and cut the peppers into pieces. Cut bacon into 8 thin pieces. Put paprika, bacon and meatballs alternately on 4 skewers. Grill the skewers under the hot grill for 10 minutes, turning from time to time.
Arrange the tomato rice with the skewers on plates. Garnish with marjoram.
