In a bowl, combine the tuna, breadcrumbs, egg, garlic, lemon juice, parsley, salt, and pepper.
Mix well until the ingredients are fully combined.
Form the mixture into small patties, about 2-3 inches in diameter.
Heat the olive oil in a skillet over medium heat.
Cook the patties for about 3-4 minutes per side, or until golden brown and cooked through.
Serve hot with a wedge of lemon or your favorite dipping sauce.
