Preheat your oven to 425ºF and get out a cast iron skillet or baking dish to bake the chicken.
Season the chicken in a marinade by combining orange juice, cilantro, coconut aminos, lime juice, minced garlic, cumin, smoked paprika, chipotle chili powder, salt, and pepper in a bowl. Add the chicken to the bowl and marinate for up to 24 hours in the fridge, if desired. I try to put it in the marinade about 2 hours before making this recipe.
Make the mango salsa by chopping the mango, purple cabbage, purple onion, and cilantro. Add lime juice, salt, and minced garlic. Mix well and set aside.
Bake the chicken for about 20 minutes, then broil for the last 5 minutes until cooked through.
Let the chicken rest for 5 minutes, then slice or shred it.
To assemble the tacos, divide the chicken among the tortillas and top with mango salsa, avocado, jalapeño, feta or cotija cheese, and fresh cilantro. Enjoy!
