Roast the chicken using this recipe or use a store bought rotisserie chicken and remove the skin and bones from the meat.
Chop up the roasted chicken along with the cilantro, red onion, lime juice, oregano, cumin, garlic powder, sea salt, and freshly cracked pepper, to taste. Mix thoroughly until well combined. Taste & re-season if desired. Heat the chicken (covered with a paper towel) for a 30-45 seconds in the microwave right before serving.
Heat the flour tortillas, wrapped in a towel, for 30-45 seconds or until warm and pliable. Spread the chicken mixture down the center of the tortilla then top with lettuce, sharp cheddar, tomatoes, green onions, olives, and avocado. Serve with a side of salsa and sour cream if desired. Enjoy.
