I actually purchased and tried the new chilled prepared food product "Charcoal Grilled Pork Hatsu with Miso Sauce" sold at FamilyMart (Famima). The purchase price is 328 yen (tax included).
Sumibi-Yaki Pork Hatsu Miso Dare
Sumibi-yaki Pork Hatsu Miso Dare is made with pork hatsu grilled over charcoal and seasoned with a sauce made of miso, sugar, and gochujang. The triangular three-dimensional package is a landmark. Before eating, heat the entire bag in the microwave.The pork belly is cut like a diced steak and has a crunchy texture. The generous amount of sauce with miso and gochujang (red pepper paste) gives it a delicious and consistent taste. Serve it over rice and sprinkle with green onions or shichimi pepper to your liking, and you've got yourself a bowl of rice! This is an excellent dish as a side dish for white rice or as a snack for drinks. You can open the pack and eat it as is, so there is no need to wash anything.
The "Charcoal Grilled Pork Hatsu with Miso Sauce" from Famima looks like a good accompaniment to a night of drinking. If you see it, pick it up!
