It is well worth making sandwiches for the freezer if you eat packed lunches regularly. Use firm slices of bread and spread with softened butter right to the edges. Wrap filled sandwiches in plastic freezer film to keep them separate, then pack in plastic freezer bags.
Use cheese, meat, fish or pate for the fillings and avoid hard-boiled eggs which can go rubbery, mayonnaise which curdles, and fresh salad which goes soggy. Keep sandwiches in the freezer for no longer than two months. You can let them thaw in their wrappings for 3 hours or so during the morning. Transport them in a rigid, plastic box to avoid damage.
