Cut the onions into half rings and boil them in a small amount of water for 2 minutes.
Cut the egg white into tiny cubes.

Combine rice, shrimps, egg whites and onions. Add seasoning as the dressing.
Fry some sesame using the dry pan for about 1-1,5 minutes and then sprinkle our salad with it ( there is no need to fry the sesame, though).
