Peel and finely chop the onion. Peel the garlic and press it through a garlic press. Heat oil in a pan, fry minced meat in it while turning, add onions and garlic.
Stir in the tomato paste. Add rice and fry until transparent. Deglaze with 450 ml broth and simmer covered for about 18 minutes. Meanwhile cut the peppers in half lengthwise, clean and wash them. Put the peppers in an ovenproof dish.
Bring the rest of the stock to the boil. Stir peas into the rice and season with salt, pepper, paprika and sugar. Fill the rice mixture into the pepper halves, sprinkle with the cheese and pour the hot stock into the mould.
Bake the stuffed peppers in a preheated oven (electric cooker: 200°C/ gas: level 3) for about 20 minutes. Serve garnished with parsley as desired.
