This document describes 5 types of cold sandwiches: open-faced sandwiches which use one slice of bread with toppings, regular sandwiches with two slices of bread that can be toasted, pinwheel sandwiches made by spreading filling on a long slice of bread and rolling it up, tea sandwiches which are small and delicate with crusts removed, and multi-decker sandwiches with multiple slices of bread and fillings. The document instructs students to get into groups and choose a type of cold sandwich to make which they will be graded on.
