Measure flour onto a dough board and create a well in the center.

Add egg and salt to the well.

Knead the mixture well until the dough becomes smooth.

Let the dough stand for a few minutes to rest.

Roll out the dough thinly.

Cut the dough into small squares to create noodles.

Cook the noodles in boiling water for approximately 10 minutes, or until done.

Drain the cooked noodles.

Add the drained noodles to the prepared sauerkraut and onion mixture, then saute.
