# How-To Steps:

01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or foil for easy cleanup.
02 - In a large bowl, mix olive oil, chili powder, ground cumin, smoked paprika, garlic powder, onion powder, dried oregano, cayenne pepper (if using), salt, black pepper, and lime juice until well combined.
03 - Add sliced chicken, bell peppers, and onion to the bowl. Toss thoroughly to coat all pieces evenly with the marinade.
04 - Spread the marinated chicken and vegetables in a single layer on the prepared baking sheet to ensure even roasting.
05 - Place the baking sheet in the preheated oven and roast for 22 to 25 minutes, stirring once halfway through, until the chicken is fully cooked and vegetables are tender with slight charring.
06 - Remove from oven and serve immediately with warmed tortillas and desired toppings such as cilantro, lime wedges, sour cream, salsa, or guacamole.

# Expert Tips:

01 -
  • One pan means one mess, and honestly, that's worth more than gold on a Wednesday night.
  • The spices do all the work while the oven does the heavy lifting, leaving you free to breathe.
  • Colorful peppers roasted until they're slightly charred taste so much better than anything restaurant version you've tried.
02 -
  • Don't slice your chicken too thin or it'll dry out before the peppers even caramelize—aim for strips about the width of your pinky finger.
  • The halfway stir is not optional; it's the difference between evenly roasted and unevenly cooked, and it takes 10 seconds.
03 -
  • If your peppers aren't browning as fast as you'd like, spread them out more strategically or raise the oven temperature by 10 degrees—browning equals flavor.
  • Slice your chicken against the grain if you want it tender, and keep all your pieces roughly the same thickness so nothing cooks faster than something else.
