Heat large soup pot, add oil, and cook chopped onions about 2 minutes, until barely starting to color.
Add garlic and saute 2 minutes more, then add paprika (and caraway if using) and saute 1 minute more.
Add ground beef to pot and cook until beef is nicely browned.
Add beef stock and beef flavor base to soup pot. Add canned tomatoes, cabbage and 2 cups water to soup pot and start to simmer.
Let the soup simmer on very low heat for 30-40 minutes.
Taste for seasoning and add more paprika if desired. I personally think you can never have too much paprika in a soup like this.
Then add diced red peppers and simmer about 30-40 minutes more. Serve hot, garnished with sour cream if desired.
This freezes very well.
