8 slices bread

1/3 cup mayonnaise

juice of 1/2 lemon

1/4 cup red onion (finely chopped)

  4. On one side of each bread slice, put some butter. As for the unbuttered side, top with about 1/2 c. of the tuna salad, tomato slices, and a couple slices of cheddar cheese. Put the buttered slice on top and make sure that the side with the butter is facing up.
  5. Repeat steps with the rest and arrange them on a baking sheet.
  6. Bake for about 5 minutes or until the cheese starts to melt.
  7. Serve.


If using tuna chunks, use a fork to break them up. You can omit the red pepper flakes if you are not into it.

This tuna melt sandwich recipe involves very simple ingredients. I’m sure you have most of them laying around in your kitchen. But in case you are missing something, you can always use a substitute. For instance, if you don’t have bread slices, you have the option to utilize English muffins instead.

You can also have a so-called open-faced sandwich wherein you will only have to use the other half of the English muffin or one slice of bread. That right there will help reduce the calories!
