Thaw shrimp according to package instructions.

Place the olive oil, lime juice, orange juice, 1 tablespoon jerk seasoning and brown sugar in a large bowl and whisk well to combine. Add the shrimp and toss well to coat, then cover with plastic wrap and marinate at room temperature for 30 minutes.

Preheat the grill to medium high. Skewer the shrimp, pineapple, bell pepper and red onion onto the skewers, and sprinkle the shrimp with the remaining 1/2 tablespoon jerk seasoning on both sides.

Grill for 3 minutes until charred, then flip and grill 2-3 minutes longer, or until shrimp is opaque and the tail curls to meet the head. Serve the shrimp with additional lime wedges and cilantro if desired. Enjoy!
