Slightly spicy grilled pork burgers are topped with a sweet and zesty pineapple salsa.
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.
