What tuna to use for a tuna melt:

The type of tuna matters! You will want to use a good quality canned tuna packed in olive oil for this recipe. The tuna that is packed in olive oil tastes so much better in my opinion and is not as fishy as the tuna packed in water. 

I love the Genova brand. It’s an Italian canned tuna and you can find it at most grocery stores. If you can’t find it you can use any other good quality tuna packed in olive oil. 

Ingredients you will need for open faced tuna melts:

canned tuna packed in olive oil: This really makes a difference in flavor! The tuna that is packed in olive oil is a lot less fishy in my opinion. I like the Geneva brand or Wild Planet Tuna 

white onion: The white onion adds a delicious flavor and a little crunch. 

celery: Celery adds a delicious crunch to the tuna salad. 

dijon mustard: You can also use a whole grain mustard as well. 

mayonnaise: This adds a little creaminess. You can leave it out if you don’t like mayonnaise. 

good quality pickles: Grillo’s brand is my all time favorite. The quality of pickles really makes a difference. 

lemon juice and zest: Adds so much bright flavor, especially the lemon zest. 

salt and pepper: Can’t go anywhere without salt and pepper.
