Put the rice in about 300 ml boiling salted water, cover and let it swell for about 20 minutes at low heat.
In the meantime, I wash the peppers and cut off a lid on each (see left). Clean the lid and the peppers. I cut the flesh of the lids into fine cubes. Peel and finely dice the onions and garlic.
Clean, wash and cut the spring onions into rings. I put a handful of the green spring onion rings aside for garnishing.
Dissolve the vegetable stock in approx. 350 ml hot water. Heat 1 tablespoon of oil in a frying pan. Fry the minced meat for about 5 minutes. Now I add the paprika cubes and half each of the onion and garlic cubes and fry everything.
Season with 1 tsp. oregano, salt and pepper. Stir in ketchup, tomato paste and approx. 150 ml stock. Add spring onion rings. Bring everything to the boil and simmer for 2-3 minutes.
I may let the rice drip off a little more. Then I mix it into the mince and fill everything into the peppers. I put the stuffed peppers in an ovenproof dish (approx. 20 x 20 cm) and pour on the remaining stock.
Cook in the preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer) for approx. 50 minutes.
For the tomato sauce, I sauté the remaining onion and garlic cubes in 1 tablespoon of hot oil. Add the chopped tomatoes and season everything with 1 teaspoon oregano, salt, pepper and a pinch of sugar. Simmer open for about 10 minutes.
Finally, I taste the sauce and sprinkle the braised peppers with the green leek and onion rings. I add the sauce separately.
