Not every bun from an Asian bakery is sweet.
We picked up a few random savory buns just because. Many Asian bakeries have low price points for individual items making them ideal places to experiment with random selections.
In this case, the “hot dog bun” turned out to be pretty much exactly what it claimed: a hot dog in a bun. The bread was sweet and soft. I think I once ate something similar to this on an airplane, although overall this was a better experience.
The below bun was a “ham bun,” which to me seems pretty much like a warm ham and cheese sandwich. Still, I enjoyed it.
