In a large saucepan, cook bacon over medium heat until crisp. Remove to paper towels; drain, reserving drippings. Crumble bacon and set aside. In the drippings, saute the onion, celery and garlic powder until vegetables are tender.
Add the beans, picante sauce, broth, parsley and bacon; bring to a boil. Reduce heat; simmer, uncovered, for 10-15 minutes or until flavors are blended. Season to taste with pepper sauce if desired. Ladle into bowls and top with cheese. Serve with tortilla chips.
