For beef strips with noodles, first cook the noodles in salted water according to package instructions until al dente.
Wash the bell bell pepper, remove the seeds and cut into strips. Drain the cucumbers and cut into strips as well. Trim the beef if necessary and cut into thin strips. Finely chop the parsley.
Heat the oil in a pot and brown the beef strips in it. Add the bell bell pepper and water. Put the lid on and cook for about 5 minutes. Then add gherkins and season with salt and pepper.
Divide beef strips with noodles on plates and serve garnished with sour cream and parsley.
