Hamada-ya croquette bread

Hamada-ya croquette bread. You can purchase this at Mitsuwa or Marukai supermarket. $1.50.
What is it? Well, it's croquette! Sounds crazy? Croquette in bread? That's Japanese style.
Now, this bread had less taste than I thought. OK, almost no taste.
Maybe it needs to have more sauce on croquette. I see just a little bit of sauce on the bottom, but you can't taste that.
