Chop the fermented cowpea into tiny pieces, about ¼ inch long. Finely chop the ginger. Set both aside.
To the minced chicken add the white pepper, five-spice, both types of soy sauce, and cornstarch. Combine well. Add 2 Tbsp oil and stir to combine.
Heat oil in a wok. Once hot, add the chicken mixture. Cook, breaking chicken up into bits until fully cooked through. Remove from wok and set aside.
Heat a little more oil in the same wok. Add dried chilis and fry for one minute before adding garlic, ginger, green onion, and broad bean chili sauce. Stir-fry till fragrant.
Add cowpeas and chicken. Stir fry 1-2 minutes or until flavors come together.
Serve warm over cooked white rice!
