Boil the carrot, eggs and potatoes, then peel or peel and dice.
In a shallow bowl, layer the potatoes, diced onion, tuna, eggs (save one egg yolk) and carrots. Brush each layer with a little mayonnaise, the top layer must be completely covered with the mayonnaise. Now crumble the saved egg yolk and sprinkle it on the salad. Garnish with olives and stick the chips in on the edge of the bowl like sunflower blossoms.
