For an extra layer of flavor, consider adding a thin spread of Dijon mustard to the bread before adding the tuna mixture. Use a microplane to zest the lemon for the finest texture and most intense flavor. Freshly baked bread is always best, but if using pre-sliced bread, opt for a thicker cut to prevent the sandwiches from becoming soggy. Feel free to substitute the Gruyère with another cheese of your choice such as provolone or Monterey Jack.
