Brush the potatoes vigorously under cold water. Cut into slices of about 1 cm thickness and wrap in a damp cloth. Clean and wash the beans. Peel and chop the onions and fry them in hot fat.
Add the beans and a good 1/8 litre of water. Season with salt and stew covered for about 15 minutes. Wash meat if necessary and dab dry. Cut into 4 equally sized pieces. Season with salt and pepper and wrap with bacon.
Heat 1-2 tablespoons of oil in a frying pan and fry the fillets for 12-15 minutes while turning. Wash and dice the tomatoes and add to the beans. Stew everything for about 3 minutes. Wash parsley, dab dry and chop except for a little bit for garnishing.
Mix into the bean vegetables, season with salt and pepper and braise for another 3 minutes. Arrange the vegetables on an ovenproof dish and arrange the fillets on top. Add wine and cream, bring to the boil and season to taste with salt and pepper.
Pour over the meat and sprinkle with cheese. Bake in the preheated oven (electric: 225 °C/ gas: level 4) for 10-12 minutes. Heat 3 tablespoons of oil in a pan. Fry the potato slices for 10-12 minutes while turning them until crispy.
Season with salt and pepper. Arrange potatoes as you like on the plate and serve garnished with the rest of the parsley.
