Cut the fillets into 4 pieces, season with salt, pepper and wrap each with a slice of bacon. Spread a little butter on an ovenproof dish, place the fillets in it and put them in the oven, which has been preheated to 200 degrees. Season the cream with tomato paste, salt, pepper, paprika and oregano, heat and after 20 minutes pour over the loin. Let cook for another 15 minutes. If you want, you can bake the whole thing with grated Gouda cheese.
