Ingredients You'll Need

- Bell Peppers: Adds a slightly sweet and crunchy texture. Use any color you like, or a trio for a more colorful dish.

- Olive Oil: Helps coat the chicken and vegetables and adds a bit of healthy fat to the dish.
- Fajita Seasoning: Adds a savory and slightly spicy flavor to the chicken and vegetables. Taco seasoning will work great too.
- Tortillas for serving.
