Add butter and beef to the pot and cook over medium-low heat until the beef is about halfway cooked.
Add carrots and onions to the beef and sauté. Cook until the onions start to turn sweet and translucent.
Add tomatoes and cabbage, stirring to prevent the beef from burning.
Once the cabbage cooks down a bit and creates more room in the pot, add 250ml of water and bring to a simmer. Continue cooking until the cabbage is further reduced.
Cover with a lid and simmer until the water and vegetables are at a similar level.
