Season the chicken liberally with five spice powder, paprika and salt. Spread on a flat layer on a baking sheet and slide into a preheated oven at 375 degrees for approximately 20 minutes.
While chicken bakes, mix the remaining ingredients in a small sauce pan over medium high heat. Once it begins to bubble, reduce to a simmer and cook until it begins to thicken.
Remove chicken from the oven and drop the pieces into the sauce. Coat in the sauce, cover and simmer another 5-10 minutes until sauce gets thick and dark and coats the chicken. Remove from the sauce pan and sprinkle with scallions.
