In large stock pot, brown the ground beef. When it is close to being finished, add the onions and cook until the beef is browned and the onions are translucent. If you use lean ground beef, there is no need to drain. (If you use a fattier ground beef, it's a good idea to drain the grease) Add in the chili seasoning and chili powder and stir well. Next add the remaining ingredients. Let simmer for 10 minutes. Serve while hot! You can add cheese, crackers, chopped onion, or even some sour cream to give it an extra kick!
