Fillet prepared according to this recipe turns out to be incredibly tender, very juicy and flavorful. If you do not take into account the time of marinating, then cook this dish quite quickly. Very tasty, try it!
Put the sliced fillet in a bowl. Add vegetable oil, soy sauce, salt and spices. Stir. Cover with cling film and leave to marinate at room temperature for at least 30 minutes. I usually leave it for 1 hour.
Cut the onion into quarter rings not too thinly.
Wash the Apple, remove the seeds, and cut into slices.
In a mixture of butter and vegetable oil, fry the onion until transparent.
Add the marinated meat.
Cook for 5 minutes over high heat, stirring, until the meat is lightly browned.
Then add the Apple. Reduce the heat, cover and simmer for 10 minutes.
