Halang-halang literally means spicy-spicy in Cebuano. In some parts of Mindanao, it's a chicken dish with coconut milk and chili. But in Oroquieta City, halang-halang is a spicy clear beef broth which is served together with pork and chicken barbecue, and puso (rice steamed in coconut leaves).
If you happen to be in Oroquieta City, make sure to drop by the halang-halang strip beside the city plaza. Make sure you're there late in the afternoon or early in the evening because the halang-halang and barbecue run out really quick especially in the more popular stalls.
I discovered that the hard way since we went out for dinner quite late and ended up missing the delicious barbecue in one of the stalls. So I made sure to go again the next day, this time in the afternoon, for another serving of halang-halang.
