Step 1

Preheat your oven to 425° Fahrenheit. Divide the chicken, bell peppers, and onions between two rimmed half-sheet pans.

Step 2

In a small bowl, whisk together the fajita seasoning and vegetable oil. Drizzle half of the mixture over each of the sheet pans. Toss the chicken and vegetables until well coated in seasoning.

Step 3

Place both sheet pans in the preheated oven. Roast for 10 minutes.

Step 4

Turn on the oven’s broiler. Broil the fajitas, checking and stirring every 60-90 seconds, until charred to your liking (about 3-5 minutes total).

Step 5

Serve with flour tortillas and choice of toppings.
