Start by rinsing the basmati rice under cold water until the water runs clear. Cook the rice according to package instructions.
In a small bowl, combine 2 teaspoons of mojo rub with 1 tablespoon of olive oil, the minced garlic, and a pinch of salt and pepper. Rub this mixture over both sides of the tilapia filets. Allow to marinate for at least 15 minutes.
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced red onion and sauté for about 3-4 minutes until translucent. Stir in 2.5 tablespoons of finely diced jalapeño and cook for an additional 2 minutes. Remove the sautéed veggies from the skillet and set aside.
In the same skillet, add another tablespoon of olive oil. Once hot, carefully place the marinated tilapia filets into the skillet. Cook for about 3-4 minutes on each side or until the fish flakes easily with a fork.
Prepare the pineapple salsa by combining the diced pineapple, remaining jalapeño, chopped cilantro, the juice of 2 limes, and salt to taste in a bowl. Mix well.
To serve, plate a scoop of basmati rice, top with the blackened tilapia, and spoon the sautéed onions and jalapeños over. Finish with pineapple salsa and cilantro. Enjoy with lime wedges.
