Peel and wash the asparagus. From the carrots, cut the green to 1 cm. Peel and wash the carrots. Wash and clean the beans and break them once. Wash the fillet of beef, dab dry and flatten a little.
Heat the oil in a pan and fry the fillet all around in about 3 minutes. Season with salt and pepper. Then fry over low heat for 10-11 minutes. Turn from time to time. Wrap the meat in aluminium foil and let it rest for about 10 minutes.
In the meantime, cook the vegetables separately in a little boiling salted water. (Beans 8-10, carrots and asparagus approx. 10 and peas 5 minutes.) Drain vegetables and arrange with the fillet on a preheated plate.
Foam fat in a pot and pour over the vegetables. Serve garnished with parsley. Potato croquettes taste good with it.
