In Argentina, the matambre is served as a steak, but is not the common method for serving matambre. The more common way that matambre is used in serving it as "matambre relleno". The ingredients vary some from province to province , but the most common ingredients for matambre are whole carrots, whole, hard-boiled, eggs, and plenty of black pepper. These ingredients are then rolled up inside of the matambre sheet and sewn or pinned together to keep the rolled matambre from coming unrolled. It is then boiled in milk, sometimes just water, and roasted in the oven. After it is removed from the oven and cooled, it is sliced into thin pieces of lunch meat and served inside of a toasted French roll with mayonnaise, and sometimes Argentine chimichurri, as a condiment.
Another flavour of matambre is the one called "matambre a la pizza" which is prepared in a similar way but instead of being rolled it is topped with pizza ingredients like tomato sauce and mozzarella.
