Preheat oil in wok. Stir fry meat until opaque (if not pre-cooked). Stir-fry egg, then add carrots and onion (and meat if precooked); cook about 30 seconds. Add remaining ingredients and stir-fry until cabbage is wilted. Wrap in to egg roll wrappers, and garnish with mushi sauce, sesame seeds, and shredded green onion.
