Preheat oven to 400 degrees F.
In a small bowl, combine the soy sauce, brown sugar, ginger, garlic, and vinegar. Set aside at room temperature.
Generously brush the meat with some of the dressing and place on a baking sheet. Roast meat for about 30 minutes. Remove from oven and cool.
When the meat is cool, cut into 1/4-inch strips. In a large bowl, combine the savoy and purple cabbage. Add the green onion and cilantro. Add the beef and enough dressing to thoroughly moisten. Add 1 1/2 tablespoon of the sesame seeds and toss again. Put on a plate. Top with remaining sesame seeds and the fried won tons.
