Rub the meat with pepper and marjoram and stew in 200 ml of wine for about 20-30 minutes, keep warm. Cut the bell pepper into strips and sauté with the leek rings, the chopped onion and the sliced mushrooms. Dust with flour, add tomato paste and deglaze with the rest of the wine, stew for 5-10 minutes (depending on taste). Cut the meat into slices, pluck the basil and mix with the vegetables, season again with salt and pepper to taste, pour the vegetable mixture over the smoked ham, cover with cheese and bake in the oven.
A mashed potato, refined with fried onion and mushroom pieces, tastes delicious with it.
