Rub all but 2 tbsp of the jerk seasoning on the pork. Add 1 tbsp of the oil to your pot, heat it, and brown the pork.
While the pork is cooling, heat the remaining oil in the same pot. Next, cook the onion and bell peppers in the hot oil until softened. Add all the spices and remaining jerk seasoning. Stir continuously for one minute.
Add the tomatoes and chicken drippings. Simmer for 20 minutes over low heat.
While the simmer is going, dice the pork into 1-inch cubes.
After the 20 minutes are up, mix in the pork. Simmer for 15 more minutes.
