Shred the carrots with a grader or with a food processor (or with your kitchen knife). Slice the onions thinly and soak them in water briefly, then leave them in a strainer.

Mix the * marked ingredients in the order written, and make a dressing.

Mix the carrot, onion and tuna in a bowl and toss it with the dressing. Set them in your salad bowl/plate and garnish with coriander.
