Mix a marinade from sugar, oil, tomato paste, salt and pepper. Rub the chops with the marinade. Finely chop the onion. Core the peppers and cut into small pieces. Cut the mushrooms into slices.
Preheat the oven to 200 ° C (convection 180 ° C). Heat some oil in a pan. Sear the chops for 2 minutes on each side, then place them on a baking tray and finish cooking in the oven for 10 minutes.
In the meantime, sauté the onion, peppers and mushrooms in the frying fat and dust with flour. Add the water and simmer for about 5 minutes. Season with salt and pepper and add the chopped parsley.
Serve the chops with the sauce. Basmati rice or French fries go well with it.
