First mix the tuna and mayonnaise. Then add pepper and salt to taste until you come up with something that looks like this. Put a lil less mayonnaise so that it will not spill out of the cucumber.
Prepare the cucumber. Cut it into half and then scrape the middle part.
Put the tuna spread that you made earlier on top.
Add some cheese on top.
Here is my finished product. I used coastal cheddar cheese but you can put any kind of cheese that you like. You can also try to cut it into pieces.👌👍
