Both salads are washed, their leaves are dry and tear into a bowl. They add chopped onions, boiled corn (can be used canned), diced apple, grated eggs (one is allowed to decorate the top) and tear to shreds herring. Make a dressing of salt, olive oil, lemon juice and balsamic vinegar and pour it with salad. Depending on the amount of lemon flavor and balsamic vinegar can be reduced to not very sour. Decorate with remaining egg and olives.
