Add shrimp, pineapple slices, red onion, jalapeno, soy sauce, olive oil, Jamaican jerk seasoning, and salt to a large resealable baggie. Seal the bag and toss, until the shrimp and veggies are evenly coated in oil and seasoning. Allow shrimp to marinate at room temp for about 15-20 minutes.
Meanwhile, preheat oven to 425 F, and line a baking sheet with parchment paper for easy cleanup.
Spread the shrimp, veggies, and marinade in a single layer on the prepared baking sheet. Bake in preheated oven for 13-15 minutes, or until the shrimp are cooked through and the red onions have softened to your liking.
Drizzle shrimp with lime juice and cilantro, toss to combine. Serve over rice with additional limes, and enjoy!
