Bring a large pot with 8 cups water to a boil. Add scallions, thyme, rosemary, quartered onion, whole scotch bonnet, smashed garlic, allspice berries, and Better Than Bouillon. Add the turkey wings, reduce to a steady simmer, and parboil for 20 minutes.
Remove wings to a tray and let them cool slightly. Strain and reserve at least 1 cup of the aromatic stock for the pan.
Pat the wings dry. In a large bowl, season with Walkerswood jerk marinade, Walkerswood jerk sauce, green seasoning, complete seasoning, adobo, smoked paprika, and kosher salt. Toss until every piece is well coated.
Lay the sliced red pepper, green pepper, and white onion in a 3-quart roasting pan or baking dish. Place the seasoned wings on top. Pour about 1 cup of the reserved stock into the pan around the wings.
Cover tightly with foil and bake at 375°F for 40 minutes.
Remove the foil, flip the wings, baste with pan juices, and bake uncovered for 15 minutes, or until the skin is golden and lightly crisp. Baste once more before serving if you like.
