# Step-by-Step Guide:

01 - Heat the oven to 425°F and line a large baking sheet with parchment paper or foil to facilitate cleanup.
02 - In a large bowl, combine olive oil, chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, optional cayenne, salt, pepper, and lime juice.
03 - Add chicken strips, sliced bell peppers, and onion to the bowl and toss until all ingredients are evenly coated with the marinade.
04 - Spread the marinated chicken and vegetables in a single layer on the prepared baking sheet.
05 - Place the sheet pan in the preheated oven and roast for 22 to 25 minutes, stirring halfway through, until the chicken is fully cooked and vegetables are tender with slight charring.
06 - Remove from oven and serve immediately with warm tortillas and desired toppings.

# Additional Tips::

01 -
  • One pan means one cleanup, which feels like a small miracle after dinner.
  • The chicken comes out tender and full of flavor, never dry or bland.
  • Colorful peppers and onions get caramelized edges that taste almost like candy.
  • Ready in 40 minutes flat, perfect for nights when you're hungry now, not later.
02 -
  • Don't skip the halfway stir; it's the difference between perfectly cooked chicken and overdone edges with an underdone center.
  • If your chicken pieces are thick, cut them thinner so they finish at the same time as the vegetables.
03 -
  • Slice your chicken slightly thinner than you think you need to; it cooks faster and stays juicier.
  • Let the spices toast for a few seconds in the oven before tossing everything together if you want even deeper flavor.
