Sardine Sandwiches

The sardine paste can be prepared up to 2 days in advance and stored in an airtight container in the refrigerator. Add the lettuce pieces just before spreading on bread to maintain freshness and prevent wilting. Bring to room temperature for 15 minutes before using for easier spreading.

Store assembled sandwiches wrapped tightly in plastic wrap in the refrigerator for up to 4 hours before serving. The sardine paste alone will keep for up to 3 days refrigerated in an airtight container. Do not freeze, as the texture will become grainy and watery upon thawing.
