The Filipino version is called bistek Tagalog, a dish made of strips of salted and peppered sirloin beef, usually flattened with a meat tenderizing tool, slowly cooked in soy sauce, calamansi juice, garlic and onions, a specialty of the Tagalog region.[1] The onions are usually cut into rings, and are added raw when the dish is either already cooked, or almost cooked for the onions to soften but maintain its crunchiness. Bistek Tagalog is known in the Spanish-speaking world as bistec encebollado or bistec tagalo. It is usually anglicized in Philippine English as "beefsteak".
