Prepare the ingredients as shown in the picture, starting from the top left: dried Italian parsley, canned tuna, chopped onion. From the bottom left: whole black peppercorns, capers, mayonnaise.

Before starting, you can chop the capers.

Next, prepare a mixing bowl and a mixing spoon.

Let's start making it! Basically, just mix all the ingredients together. But for those who want more details, Teacher Guan will break it down for you. The order doesn't matter; add whichever ingredient you want first.

Add the chopped onion.

Add the chopped capers.

Add some of the black peppercorns from the recipe.
