Cut a wafer-thin lid off the green peppers. Core and wash the peppers. Finely dice 1/2 each red and yellow pepper. Coarsely chop the other half. Knead the finely diced peppers, minced meat, egg, mineral water, 1 teaspoon of salt and 1 pinch each of pepper, curry and sweet paprika.
Chop the herbs. Mix half of them into the meat. Fill the green peppers with it. Wash, skin and roughly dice the tomatoes. Prepare tomato sauce according to instructions. Place in an ovenproof dish and place the peppers in it.
Spread the remaining vegetables all around and cover the dish. Cook in the preheated oven (electric cooker: 200 °C/ gas: level 3) for about 45 minutes. Remove the lid for the last 15 minutes. Cook the rice in boiling salted water for 15-20 minutes.
Serve the peppers sprinkled with remaining herbs. Serve with rice.
