Saute carrots, celery, onion in butter. Add flour and chicken broth and stir until smooth. Add dried herbs. Bring to a boil. Add Cheese Whiz and cheddar cheese; continue heating until all the cheese has melted. Add beer. Heat to serve.
Note: If you want it thicker reserve some of the chicken broth before you add it, and mix with corn starch and add it along with the flour before the cheese.
