Mix all the ingredients together in a bowl (minus the tortillas and cheese) and marinate for at least 4 hours
Preheat the oven to 400 degrees, and add the chicken to a greased baking sheet. Bake for 20 minutes until cooked through and shred
Increase the temperature to 425 degrees, line a baking sheet with corn tortillas and spray with cooking grease. Heat for 2-3 minutes (this will make them pliable)
Load on some cheese, chicken, then more cheese. Fold over and bake for 15 minutes until nice and crispy.
Top with avocado crema, diced tomatoes and cotija cheese.
