I made menchi (minced) katsudon.
It is usually simply the normal tonkatsu used for katsudon, but in an attempt to impress my friends (which I believe succeeded), I decided to try using ground pork for the "tonakatsu" in the katsudon.
Strange enough, I found it a little bland but everyone else liked it. Maybe it was because I skimped on the sauce for my own serving because I wanted everyone else (around 6 people) to have as much of the sauce as possible.
The minced meat katsu worked great though, since it does not require one to bite into the meat. Tender meat (like black pig from Japan) is great for tonkatsu, but I can't really get it here. The menchi katsu was a great substitute.
It was much better on the katsu sandwich I made the day after though.
I realize now that I am fantastic at making dishes found in anime (curry, nikujaga, tonkatsu, katsudon, napolitan pasta, okonomiyaki, hamburg etc.), and that made me laugh.
EDIT: for hamburg (Japanese style burger steak) sauce, the easiest but really tasty shortcut is to use equal amounts of ketchup and Worcestershire sauce for the burger sauce. It is extremely easy, but a great sauce nonetheless.
