In a pot, boil the potatoes with a little water and salt.

Drain the cans of tuna. Finely chop the onion, garlic, and parsley. Set aside.

Once the potatoes are cooked, peel and dice them into small cubes. Add the tuna, onion, garlic, parsley, and egg. Season with salt and pepper to taste.

Once all the ingredients are mixed, gradually add breadcrumbs until you have a dough you can shape into patties.

Fry the patties in a little oil until golden. Serve on a bed of lettuce and enjoy with Mexican-style red rice with vegetables.
