Wash and clean the beans and cook them in little boiling salted water for 8-10 minutes. Meanwhile wash the meat, dab dry and cut into 6 medallions. Season with salt and pepper. Wash and clean the chanterelles.
Peel and finely chop the onion. Wash thyme, dab dry and, except for 3-4 stems for garnishing, pluck leaves from stems. Heat 2 tablespoons of oil in a large frying pan, fry the meat for 2-3 minutes on each side, remove.
Sauté the onion in the frying fat, add the chanterelles and fry for approx. 3 minutes in the pan, turning, season with salt and pepper, remove. Heat the fat in a pan. Sauté the flour in it.
While stirring, deglaze with stock and cream and simmer for about 2 minutes. Season to taste with salt, pepper and thyme. Drain beans, quench briefly and drain well. Wrap the beans in portions with the breakfast bacon to make 4 packets.
Heat 1 tablespoon of oil in a frying pan, fry the parcels all around, remove. Put meat and beans alternately in a large casserole dish, pour thyme sauce over them and sprinkle with cheese.
Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 8 minutes, remove from the oven and garnish with the remaining thyme. Boiled potatoes taste good with it.
