Move oven rack to top position and preheat oven to broil setting.
Broil the wings for 10 minutes on each side (or until browned to your liking).
Meanwhile, mix remaining ingredients except hoisin, lime juice, sesame seeds and green onions.
Transfer the wings to a slow cooker. Add mixed sauce and stir thoroughly.
Cover and cook on low (5-6 hrs) or high (2-3 hrs).
Stir 1 time in the middle of cooking and baste wings with the sauce.
After cooking is completed, remove wings from the slow cooker and put on a serving platter. Reserve 1/4 cup of the cooking liquid from the slow cooker.
Combine the reserved slow cooker liquid with hoisin sauce and lime juice. Drizzle over the wings.
Sprinkle wings with toasted sesame seeds and green onions and serve immediately.
