Wash the meat thoroughly under running water and then pat dry, divide each half of the fillet once and brush generously with mustard.
Wrap the pieces of meat in bacon and place in an ovenproof dish. Roast in the oven preheated to 160 ° C for about 25 minutes (preheat to 180 ° C for top / bottom heat).
In the meantime, mix the cream, milk, granulated broth, cream cheese and, if available, chopped fresh garden herbs (e.g. parsley, cress, chervil, chives) into a sauce. Pour over the fillets and place in the oven for another 15 minutes.
Salt and pepper are not absolutely necessary, broth, cheese, mustard and bacon provide enough flavor.
