Instructions
Step 1

Step 10
Step 3: Arrange on Baking Sheets
Step 11
* Spread the seasoned mixture in a single, even layer across one or two large baking sheets. Do not overcrowd the pans, as this will cause the ingredients to steam instead of roast.
Step 12
Step 4: Bake the Fajitas
Step 13
* Place the baking sheets in the hot oven and bake for 20-25 minutes.
Step 14
* The fajitas are ready when the vegetables are tender and slightly browned, and the chicken is fully cooked through.
Step 15
Step 5: Warm Tortillas and Prep Toppings
Step 16
* While the fajitas are baking, warm your tortillas. The easiest way for a big batch is to wrap a stack in aluminum foil and place them in the oven for the last 10 minutes to warm through.
Step 17
* Put the sour cream, salsa, and sliced avocados into small bowls for serving.
Step 18
Step 6: Serve and Enjoy!
