Preheat the oven
Preheat your oven to 400 degrees Fahrenheit and line a rimmed baking pan with parchment paper for easy cleanup.
Prepare the ingredients
Trim and cut chicken breast into thin bite-sized pieces, then seed and cut the peppers into thin strips. Finally, cut the onion into thin strips, removing the ends and outer skin first.
Combine the mixture
In a medium bowl, combine the chicken breast pieces, cut peppers and onions, and minced garlic. Toss everything with olive oil and sprinkle with all seasoning except cilantro, stirring until well combined.
Bake the fajitas
