Heat a large skillet over medium-high heat and add olive oil.
Add diced chicken to the skillet and season with chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper. Cook for 5-6 minutes, stirring occasionally, until the chicken is browned and cooked through.
Add pineapple chunks, red onion slices, and red bell pepper slices to the skillet. Stir well to combine and cook for an additional 4-5 minutes until the vegetables are tender and the pineapple is slightly caramelized.
Warm the tortillas in a separate skillet or microwave for a few seconds until pliable.
Assemble the tacos by spooning the chicken and pineapple mixture onto each tortilla.
Garnish with chopped cilantro, sour cream, and a squeeze of lime juice, if desired.
Serve immediately and enjoy!
Notes
You can substitute fresh pineapple with canned pineapple chunks if needed. Adjust the spice level by adding more chili powder or a pinch of cayenne pepper.
