Preheat your oven to 400°F. Line a large sheet pan with parchment paper for easier cleanup.

In a large mixing bowl, combine the sliced chicken, bell peppers, and onion. Drizzle with olive oil and sprinkle generously with fajita seasoning. Toss everything together until the chicken and vegetables are evenly coated.

Spread the chicken and vegetable mixture in a single layer on the prepared sheet pan. Ensure there's enough space for even cooking and browning.

Roast in the preheated oven for 15 minutes. Remove the sheet pan, stir the mixture, and return to the oven for another 10 to 15 minutes, or until the chicken is cooked through (internal temperature of 165°F) and the vegetables are tender-crisp with slight charring.

While the fajitas are roasting, warm your tortillas. You can do this in a dry skillet over medium heat for about 30 seconds per side, wrap them in foil and warm in the oven for 5-7 minutes during the last few minutes of cooking, or microwave them briefly until pliable.

Once cooked, remove the sheet pan from the oven. Squeeze fresh lime juice over the hot fajita mixture to brighten the flavors.

Serve the sheet pan chicken fajita mixture immediately with the warm tortillas, fresh cilantro, and any desired toppings such as sour cream, salsa, or sliced avocado. Assemble your tacos and enjoy!
