Preheat your oven to 400ºF and mix all fajita spices in a small bowl.

Slice onions, bell peppers, and chicken into thin strips.

Place chicken and veggies on a large baking sheet.

Drizzle with oil, sprinkle with seasoning, and toss everything to coat evenly.

Spread the mixture in a single layer across the pan.

Bake for 35–40 minutes, stirring once halfway through for even cooking.

Once done, squeeze lime juice over everything for a burst of freshness.

Serve in warm tortillas with your favorite toppings like sour cream or fresh cilantro.
