In a small bowl, combine the oregano, chili powder, onion powder, garlic powder, paprika, salt, pepper, cumin, and parsley. Mix well.
Place 1 tablespoon coconut oil in a fry pan and add the chicken and half of the seasoning mix. Cook until chicken is done, stirring often- about 7 minutes. Remove to a bowl or plate.
Add the remaining tablespoon of coconut oil and add the onion and peppers to the pan. Sprinkle the remaining seasoning mix on them and cook until tender- about 8-10 minutes.
Serve chicken, peppers, and onions over Romaine lettuce or cauliflower rice, top with avocado if desired.
