01 - In a large bowl, combine diced chicken with cumin, chili powder, smoked paprika, garlic powder, salt, and black pepper. Toss until evenly coated.
02 - Heat olive oil in a large skillet or sauté pan over medium-high heat. Add seasoned chicken and cook for 5–6 minutes, until beginning to brown.
03 - Add onion, bell pepper, jalapeño, and garlic to the pan. Sauté for 3–4 minutes, stirring occasionally, until vegetables are just tender.
04 - Stir in diced pineapple and cook for another 5 minutes, allowing the fruit to caramelize slightly. Pour in lime juice and add half the cilantro; toss to combine.
05 - Warm tortillas directly in the pan for 30 seconds per side or wrap in a damp towel and microwave until pliable.
06 - Fill each tortilla with the chicken-pineapple mixture. Top with avocado, cheese, remaining cilantro, and extra lime wedges as desired. Serve immediately.
