Boil up just under ½ l salted water. Preheat oven: electric cooker: 175 °C/circulating air: 150 °C/gas: stage 2. Cover rice and simmer in salted water for about 15 minutes. Wash and chop parsley.
Peel and chop the onion. Wash cutlets and season with salt and pepper. Put ham double on the escalopes. Sprinkle with half of the parsley, fold over and pin.
Heat the oil in a pan and fry the escalopes in it for about 3 minutes on each side until crispy. Place on a baking tray and continue to fry in the oven for approx. 8 minutes. Add the vegetables to the rice without defrosting, cook for about 5 minutes.
For the sauce, sauté the onion in the frying fat, sauté the tomato paste, add 200 ml water, simmer for 2 minutes, season. Mix vegetable rice with butter and the rest of the parsley. Arrange everything.
