Date and Nut Sandwich

The date and walnut filling can be made up to 2 days ahead and stored in an airtight container in the refrigerator. Stir well before using, adding a teaspoon of mayonnaise if the mixture has dried out. Assemble sandwiches no more than 2-3 hours before serving to prevent soggy bread.

Assembled sandwiches are best eaten within 2-3 hours. Store wrapped individually in plastic wrap or wax paper at room temperature. The filling alone will keep refrigerated in an airtight container for up to 5 days. If sandwiches must be made further ahead, place a lettuce leaf between the filling and bread to create a moisture barrier.
