Pre-heat oven to 375 degrees F.
Mix together green onion, ginger, cornstarch, soy sauce, mirin, water, sesame oil, black bean paste, and choice of meat, then set aside. Marinate up to 8 hours.
In a small saucepan, bring water to a boil and throw the cabbage leaves in for about 2 minutes, until they begin to wilt, then remove and set aside on a dry towel.
Lay the cabbage leaves out on a work surface and place about 1/4 cup of the filling mixture in each, then roll them and place on a baking sheet.
In a small bowl combine Hoison sauce and vinegar, and then brush the mixture over the top of the cabbage rolls. Place in the oven for about 25 minutes, testing for doneness that the filling is completely cooked. Top with toasted sesame seeds and serve. Enjoy!
