Instructions
 

Preparation

  • Preheat your oven to 400°F (200°C) and prepare your vegetables and chicken.
  • In a large bowl, combine the sliced chicken, bell peppers, and onion with olive oil and fajita seasoning, tossing to coat evenly.

Cooking

  • Spread the mixture onto a large sheet pan in a single layer, ensuring not to overcrowd the pan.

Notes

For extra flavor, marinate the chicken and vegetables for 30 minutes before roasting. Adjust fajita seasoning to your spice preference.
