Spread lavash with a thin layer of mayonnaise. Sprinkle with grated cheese, chopped hard-boiled eggs. Add the layer of canned cod liver and chopped scallions. Tightly collapse the lavash or pita bread. Be careful, do not tear the flatbread. Roll the lavash roll into the food film and put in the refrigerator for 1 hour.
Cut into pieces. Enjoy your meal!!!
