5 minutes tuna salad - Super easy, super quick, super tasty

My daughter told me about this delicious tuna salad that she tasted while on vacation in Croatia. We also made it at home and it has since become one of the family's favorites. I am sharing this recipe with you now. It's super easy to make and it's ready very quickly.

150g of tuna (in brine or in oil)
