# Steps:

01 - Preheat oven to 425°F. Line a large sheet pan with parchment paper or foil for easy cleanup.
02 - In a large bowl, whisk together olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, pepper, and lime juice.
03 - Add chicken strips to the marinade and toss to coat. Add bell peppers, red onion, and pineapple chunks; toss again until evenly coated.
04 - Spread the mixture in a single layer on the prepared sheet pan.
05 - Roast for 22 to 25 minutes, stirring halfway through, until the chicken is cooked through and vegetables are tender with caramelized edges.
06 - Warm tortillas according to package instructions.
07 - Serve the chicken, pineapple, and vegetables in tortillas. Top with fresh cilantro and a squeeze of lime.

# Tips from the Pros:

01 -
  • One pan means you're done with cleanup before dessert even crosses your mind.
  • That tangy-sweet-smoky combination tastes like you spent way more time on this than you actually did.
  • The pineapple caramelizes beautifully, making every bite feel a little special.
02 -
  • Don't skip stirring halfway through—I learned the hard way that one side gets way more char than the other if you leave it untouched.
  • Cutting your chicken into thin, even strips is the secret to it cooking in exactly 25 minutes instead of some pieces being dry while others are still barely cooked.
03 -
  • Slice your chicken right before cooking so it stays fresh and cooks more evenly—thick and thin pieces will never cook at the same rate.
  • Don't crowd your sheet pan; give everything space to breathe so it actually caramelizes instead of steaming.
