Combine all ingredients in Soup Pot (no need to brown chicken). Bring to boil and skim surface a few times. After 1 hr. remove chicken and when slightly cooler, shred. Return to pot and continue to cook for another hour or longer.
While soup is cooking, prepare optional ingredients - add-ins for serving soup. All are optional - green peppers, tomatoes, onions, olives, cheddar or jalapeno cheese OR if in a hurry use a container of salsa.
To serve - Into each Tortilla Shell add a tablespoon each of desired add-ins, ladle in soup, top with cheese, sour cream and tortilla strips. Expect to hear "Wow's" when you serve.
FOR BEEF SOUP - INSTEAD OF CHICKEN, USE 2 LBS. BEEF CUBES AND ADD 2 TABLESPOONS WORCESTERSHIRE SAUCE.
