Jamaican Jerk Pork Stir-Fry

I had photocopied this recipe from a cookbook that I borrowed in 2001, I think? This is the first time I made this dish. The pork was spicy, but had a great flavor, as it was coated with the multitude of spices that make up "jerk" seasoning. It was stir-fried with apples and sweet potatoes (I used a yam) and served over brown rice. (As an aside, brown rice never comes out right when I cook it.)

This came out just shy of something pretty interesting. I might try it again with some variations?
