Prepare an "authentic" Peruvian ceviche with Gipsy Chef in a few minutes

Gipsy Chef sets out to prepare an authentic Peruvian ceviche, and says he will do it without adding anything weird (will have to see it). You can use any white fish you like, but it must be very fresh. The rest of the steps in the recipe are very easy: in a few minutes you will have a fresh and tasty dish ready that will be great for the sunniest days of spring.
