The document provides instructions for making "Mazurian sailboat" sandwiches for children. The sandwiches are made with slices of wholemeal bread, butter, boiled eggs, lettuce, tomato, and ham. To assemble, slices of bread are cut in half and buttered. Tomato and egg slices are placed on the bread to form the boat's hull. A toothpick is used to attach a slice of ham and lettuce leaf as the sail, placed on top of the egg. The finished sandwiches are presented as boats and are described as looking nice and tasting good.
