Jamaican Jerk is a spicy with a hint of sweet seasoning. If the tofu is already seasoned, it depends on how much seasoning it has as to how spicy it will be. Usually it's not too much, just a nice mild to moderate heat.
I don't know how to prepare tofu, but when I make Jamaican Jerk chicken, it is usually grilled and I serve it with things like grilled vegetables, corn on the cob, salad, seasoned rice, and sometimes grilled pineapple. We love it! Let us know how you ended up preparing it, it sounds good~
