Takway are the tendrils growing sideways from a gabi plant (more at Wyatt's Kitchen). Its outer layer is scraped off to reveal a fleshy stem. Sold mostly in wet markets but for convenience it can also be found neatly packed in groceries here in Iloilo City. It can be cooked in variety of ways but the most popular is "being sauteed with guinamos".
Simply enough, one just sautes it with pork bits then add guinamos and vinegar until it becomes tender. The result is a simple dish that would demand additional cups of rice.
