  • Griddle or Large Frying Pan


  • 1 5.4 oz can Albacore Tuna
  • 4-6 slices Easy White Sandwich Bread
  • 1 cup fresh baby spinach, packed and diced
  • 3 tablespoons Mayonnaise
  • 1 tablespoon Dijon Mustard
  • 2 tablespoons sweet pickle, diced about 1 small pickle
  • 2 tablespoons butter
  • 8 slices very thin sharp cheddar cheese or about 1/2 - 3/4 cup shredded


  • In a medium bowl, add tuna, mayo, mustard, spinach, and pickle and mix well.
  • Heat a griddle or large frying pan to medium.
  • Generously butter one of bread slices. Place two bread slices butter side down on griddle, add 2 thin slices of cheese to eat slice of bread (or about 1/4 of the total shredded cheese). Top with generous amount of tuna mixture and then with remaining cheese. Place bread on top with buttered side up. (If using smaller frying pan, cook one sandwich at a time)
  • Cook for 3-4 minutes or until buttered down side of bread is golden brown and bottom layer of cheese is melted.
  • With a large spatula, carefully flip your sandwich, careful not to spill it's contents, and cook on other side for another 3-4 minutes or until cheese is melted and bread is golden brown.


This recipe makes about 2 sandwiches that are packed full. You could definitely get 3 sandwiches out of the amount of filling, if your sandwiches are less full.  
Cheese: You can also use shredded cheese, 1/2 - 3/4 cup of shredded cheese.  
Cook Time: This will depend on how thick your bread is and how your cheese melts - which depends on how thinly it's sliced or if it's grated. Thinner bread and grated cheese will melt faster.  Cook until bread is golden brown and cheese is melted.
Substitutions: Use bread and butter or dill pickles, or pepperoncinis.  Add diced celery or diced red onion, if desired.
Make it a sub!  Use your favorite hoagie roll and make it a sub!  Melt the cheese in the broiler for about 3-5 minutes.
