In a large bowl, stir together the soy sauce, sugar, sesame
seeds,
sesame oil, shallots, garlic, and mirin. Add the meat, and stir to
coat. Cover and refrigerate for 12 to 24 hours.
Heat a large skillet over medium heat. Fry the meat for 5 to 10
minutes, or until no longer pink. Serve with salad or fried rice.
