This recipe is from the mystery "The 27* Ingredient Chili Con Carne Murders" by Nancy Pickard and Virginia Rich.
In a mixing bowl, mix ground beef,garlic powder, cumin, oregano and cilantro. Shape into 1-oz meatballs.
In a large pot, saute in the butter, the tomatoes, chilies, garlic, onions, cabbage, zucchini, and cilantro. Add the beef broth. Just before the broth comes to a bil, add the meatballs, one at a time. Add salt and pepper to taste. Simmer for 30 minutes. Top with chopped cilantro just before serving.
Note: This is even better the next day.
