Preheat your oven to 425°F.
In a small bowl, mix together the Jamaican jerk sauce and tomato sauce.
Spread the sauce mixture evenly onto the pizza crust, leaving a 1/2-inch border around the edge.
Sprinkle the shredded mozzarella cheese over the sauce.
Add the red onion, green bell pepper, and yellow bell pepper on top of the cheese.
Sprinkle the shredded jerk chicken over the vegetables.
Add the pineapple chunks on top of the chicken.
Bake the pizza in the preheated oven for 12-15 minutes, or until the crust is golden brown and the cheese is melted and bubbly.
Once the pizza is done baking, remove it from the oven and sprinkle the chopped cilantro over the top.
Let the pizza cool for a few minutes before slicing and serving.
