Over the past several years, avocado has gone from appearing only in guacamole form to making its way into a variety of dishes—and sandwiches are no exception. The rich and creamy fruit works well sliced with turkey and mashed with egg, and can be added to a cold sandwich or cooked into a grilled panini. A great substitute for mayonnaise, avocado offers a similar smoothness and mouthfeel while providing nutrients and healthy fats. From a classic turkey club to a traditional Pueblan Mexican sandwich, a variety of sandwiches and ingredients are a great vehicle for avocado.
