Procedure:
THIS RECIPE DOES NOT merely require the basic ingredients, but also a lot of imagination .... Boil the potatoes until they crumble easily and mash them with a fork. When they have cooled down, add the tuna fish (previously drained of oil), the mayonnaise (homemade with lots of lemon). Mix everything together. Season with salt and pepper and then . .. have fun! Take a long, oblong or round platter; it does not matter which as the "fish" will take on the shape you wish to give it.
Take the mixture in your hands - it's like becoming children again - and make the shape of a fish. Slice the pickled gherkins horizontally into quite thin rounds. Starting from the fish's tail, lay them one over the other to create the scales of the fish, then, with the red sweet pepper, make a nice smiling mouth and a long, majestic tail. The black olive forms the mischievous eye.
