Place the chicken, half the olive oil, lime juice, and half of the fajita seasoning in a medium bowl and toss together well. Set aside in the refrigerator while you prepare the spiralized vegetables.

Spiralize the bell peppers and onions with Blade A. Switch to Blade D and spiralize the sweet potatoes.

Heat a large skillet over medium-high heat. Once heated, add the chicken and any remaining oil/seasonings. Cook for 5 minutes per side or until chicken is cooked through and no longer pink on the inside. Set aside.

Heat the remaining olive oil in the skillet back over medium-high heat. Immediately add the sweet potatoes, onions, and bell peppers. Add the remaining fajita seasoning mix and toss well to combine. Let cook for 10 minutes or until potatoes are cooked through, tossing occasionally.
