Step 1

Preheat oven to 400°F (200°C). Spray an 17 by 12-inch rimmed baking sheet with non-stick cooking spray.

Step 2

For the seasoning: In a small mixing bowl whisk together chili powders, cumin, paprika, coriander, 1 1/2 tsp salt and 1/2 tsp pepper, set aside.

Step 3

For the fajitas filling: Spread bell peppers and yellow onion onto baking sheet.

Step 4

Top with chicken strips then sprinkle garlic and seasoning evenly over chicken strips.

Step 5

Drizzle olive oil over top then toss everything to evenly coat. Spread into an even layer working to keep chicken from overlapping.

Step 6

Roast in preheated oven, tossing once halfway through cooking, until veggies are tender and chicken has cooked through, about 18 - 25 minutes (test a few of the larger pieces to make sure they are 165 in the center).

Step 7

Wrap tortillas tightly in foil and warm in oven during last 5 minutes of fajita filling cooking.

Step 8

Drizzle lime juice evenly over top of the chicken fajita filling, sprinkle with cilantro and more salt to taste and toss to coat.

Step 9

Serve filling warm in warm tortillas with desired toppings.
