Brown hamburger in heavy skillet. Add onion and garlic;
cook until onion is tender. Add remaining ingredients and
simmer about 15 min. Preheat frankfurters and buns. Place
franks in buns; top with sauce.
Sprinkle chopped onions over top. Use yellow mustard if
desired. Some like cheese on their chilli dogs. But, if
you use cheese then the sandwich is no longer kosher.
