Heat the remaining butter. Sauté the onion cubes in it. Add flour and sweat briefly. Stir in 1/4 l water, milk, stock and chopped herbs, bring to the boil. Simmer sauce for about 5 minutes. Stir from time to time. Chop gorgonzola and melt in the sauce. Season to taste
Wash the fillets, dab dry and cut into 10-12 medallions. Wrap 1 slice of bacon around each medallion. Fry the medallions in hot oil on each side for about 2 minutes. Season and remove. Dissolve the roast with a little water and stir into the gorgonzola sauce
Spread the beans in a flat ovenproof dish. Place medallions on top. Pour gorgonzola sauce over them. Bake in the preheated oven (electric cooker: 200 °C/recirculating air: 175 °C/gas: level 3) for approx. 25 minutes. Garnish with the rest of the herbs. Serve with new potatoes
