Sheet Pan Chicken Fajitas

Step 1
Combine oil, chili powder, oregano, garlic powder, onion powder, cumin, salt, black pepper, and cayenne pepper in a large resealable plastic bag. Add chicken tenders, bell peppers, and onion; seal the bag and shake to mix. Marinate in the refrigerator, 30 minutes to 2 hours.

Step 2
Preheat the oven to 400 degrees F (200 degrees C). Line a rimmed sheet pan with aluminum foil.

Step 3
Spread chicken mixture onto the prepared pan.

Step 4
Roast in the preheated oven, stirring halfway, until chicken is no longer pink and bell peppers are softened, 15 to 20 minutes. An instant-read thermometer inserted into the center of chicken should read at least 165 degrees F (74 degrees C).

Step 5
Sprinkle cilantro and pour lime juice over chicken mixture; stir to distribute.
