How to Make Chicken Fajitas
- In a small bowl, combine chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and pepper. Set aside.
- Heat 1 tablespoon of olive oil in a cast-iron skillet over medium heat. Once the oil is hot, add the sliced bell peppers and onion. Sauté for 5-7 minutes until the veggies soften and the edges start to char.
- Stir in minced garlic and half of the seasoning mix (about 1 ½ tablespoons). Sauté for another 2-3 minutes, stirring frequently. If the pan becomes too dry, add a splash of water to prevent burning.
- Once the vegetables reach your desired doneness, transfer them to a plate and set aside.
- Wipe the skillet clean if needed, then heat the remaining tablespoon of olive oil. Add the chicken strips, the rest of the seasoning mix, and lime juice. Cook for 5-6 minutes, stirring occasionally, until the chicken is fully cooked and golden brown.
- Return the veggies to the skillet and toss everything together. Cook for 1-2 minutes to reheat the vegetables and let the flavors meld.
