In a medium, non stick skillet over medium heat, cook chicken until no longer pink and juices run clear. Drain excess fat. Cube the chicken and return it to skillet. Add onion, sour cream, cheddar cheese, parsley, oregano and ground black pepper. Heat until cheese melts. Stir in salt, tomato sauce, water, chili powder, green pepper, and garlic.

Roll even amounts of the mixture in the tortillas. Arrange in a 9x13 inch baking dish pan. Cover with taco sauce and 3/4 cup cheddar cheese. Bake uncovered in the preheated over for 20 minutes. Cool 10 minutes before serving.
