Preheat the oven to 400 degrees F (200 degrees C).

Layer pineapple and peppers on a baking sheet. Drizzle evenly with 1 tablespoon olive oil.

Bake in the preheated oven until browned, 15 to 20 minutes. Stir occasionally to prevent overbrowning.

Meanwhile heat remaining olive oil in a large skillet over medium heat. Cook and stir onion until soft, about 5 minutes.

Combine pineapple-pepper mixture, onion, orange juice, salt, and pepper in a blender or food processor. Puree until salsa is thoroughly combined. Add cilantro and blend lightly. Chill for approximately 1 hour.

Combine ground pork, seasoned salt, paprika, dill, garlic powder, hot sauce, and red pepper in a large bowl. Blend well using your hands. Shape mixture into 8 patties.

Preheat a gas or charcoal grill for medium-high heat and lightly oil the grate.

Grill burgers until browned, 5 to 7 minutes per side. Cook 5 minutes for medium-well; 7 minutes for well done.

Place burgers on buns and garnish with pineapple salsa.
