Add shrimp, 1/2 tablespoon olive oil and jerk seasoning to a large bowl and stir to combine. Place in the fridge and allow to marinate for 20 minutes.
Preheat the oven to 450° F. Prepare a large sheet pan by spreading Reynolds Wrap Non-Stick foil over it. Make sure the dull side is up as this is the side that is non-stick.
Once the oven is preheated, add sliced green bell pepper, red bell pepper, red onion and pineapple to the sheet pan with 1/2 tablespoon olive oil and season with salt and pepper. Bake in the preheated oven for 15 minutes.
After 15 minutes, remove the sheet pan and slide the peppers, onions and pineapple to one side of the sheet pan. Add the marinated shrimp to the cleared side of the sheet pan in a single layer. Return the baking sheet to the oven and bake for an additional 10 minutes, until the shrimp is cooked through.
Remove and serve with warm tortillas, lettuce wraps or over rice. Enjoy.
