Mexican Sandwich Filling

The egg-olive-pimento mixture can be ground and stored separately from the dressing up to 1 day ahead in an airtight container in the refrigerator. Add the salad dressing just before serving to prevent the filling from becoming watery.

Store the finished sandwich filling in an airtight container in the refrigerator for up to 3 days. The mixture may release some liquid upon standing; simply stir before using. Do not freeze, as the eggs will become rubbery and watery when thawed.
