I love sandwiches for lunch. They are easy to make, easy to pack for bag lunches and, using the right ingredients, can be a nutritious and healthy meal as well.

Today’s recipe is one of my favorite sandwiches, the tuna melt. I think I had my first one at my Mother-in-law’s house and fell in love with the flavor combination of tuna and melting cheese. Now that fall is here, it seemed like the perfect time to offer up a grilled sandwich that will warm you up as the days get cooler.

This tuna melt is a take on the original. I have switched out the cheddar or Swiss cheese for my new favorite cheese, Gruyere, which, by the way, melts really well, and then I’ve punched the health quotient up with some healthy spinach and whole grain bread.

I’ve also left off the mayonnaise and used the tuna straight from the can. You definitely won’t miss the extra fat and calories with all that glorious melted cheese on top.

It’s a big gooey sandwich that is filling but relatively healthy too! Just look at what this sandwich can do for you:

Tuna: High in omega 3’s which have anti-inflammatory health benefits as well as aiding in heart health. Good source of lean protein.

Spinach: High in phytonutrients, including flavonoids and carotenoids, which help protect against inflammatory problems, cardiovascular problems, bone problems, and cancers. 

Whole Grain Bread: Contains fiber which can reduce the chance of developing colon cancer as well as regulate blood sugars. It also helps you feel full longer and aids digestion. 

Gruyere: Although high on the saturated fat side, which we should keep to a minimum, this hard cheese contains no carbohydrates and provides plenty of protein and calcium. 

Hope you enjoy!

Author: Linda Warren


  • 2 slices whole grain bread
  • 1 Tablespoon butter, softened (I like Kerrygold butter)
  • 1 Tablespoon Pecorino Romano cheese, grated (Parmesan can also be used)
  • 1/2 cup Gruyere cheese, shredded
  • 1 Tablespoon onion, diced
  • 2-1/2 oz white albacore tuna, drained
  • Handful spinach leaves


  • Lay 2 pieces of bread out and butter one side.
  • Evenly divide the Pecorino Romano cheese and sprinkle on top of butter to coat. Press so it adheres to butter.
  • Place 1 slice down in skillet or on a griddle. Place half of Gruyere cheese on top of bread. Sprinkle with onions, layer with tuna, spinach and finish with the remaining Gruyere cheese. Top with other slice of bread, buttered side up.
  • Turn heat on stove to medium and cook one side until it is brown. Carefully hold sandwich together while you flip it and brown other side.
  • It is ready when browned and cheese is melted.
  • Serve with pickle slices and a piece of fruit.


You can also add a tomato to the sandwich too for additional vitamins and minerals.
