Del Pietro Ox Sirloin

Preparation:

Preparation: In an earthenware bowl, prepare a marinade as follows: 1 onion cut into slices, 1 stalk of celery also sliced, 1 carrot cut into slices, 2 tablespoons of dietary oil, half a liter of dry white wine. In the ready marinade insert the ox sirloin which you will leave to macerate for about eight hours, turning from time to time. When the meat has absorbed the aromas, take a saucepan in which the piece of meat does not occupy more than 2/3 of the capacity and heat it over a moderate heat until it has reached the right degree of heat. Arrange the sirloin in it, browning it on both sides and immediately add a ladleful of the marinade. Continue cooking for about 20 minutes, so that when cut, the meat is well pink inside. In the meantime, pour the marinade with its legumes into a pan, reduce the liquid to about 2/3 and sieve everything. At this point, slice the sirloin, overlap the slices and cover them with the sauce made from the marinade.
