We do a great tonkatsu sandwich with sweet potato fries. I make a pickled shredded cabbage and onion cole slaw that I put on the bun with the pork, tonkatsu sauce, tomato and a little mayo. I ran it as a lunch special on occasion and it sold out every time.Tonkatsu sauce is available in bottles, but it’s so easy to make I keep it on hand in the refrigerator. It lasts a long time. It’s good with scrambled eggs and hash browns.
