In a medium bowl, mix the diced pineapple, avocado, red onion, cilantro, jalapeño if using, and lime juice. Stir gently and allow it to sit for a bit so those flavors can meld beautifully.
In a small bowl, combine the smoked paprika, garlic powder, chili powder, salt, and black pepper. This blend will give the shrimp a nice kick.
Make sure to pat the shrimp dry using a paper towel, then toss them in the spice mixture until they're evenly coated. This is a key step for flavor!
Heat olive oil in a large skillet over medium-high heat. Once hot, add the shrimp in a single layer and cook until they turn pink and opaque.
Divide the cooked rice into bowls, top each with the seasoned shrimp, and finish with a generous scoop of the pineapple salsa. This step is where all the colors and textures come to life!
