In a large pot over medium-high heat, add ground beef, chopped onion, and minced garlic. Cook for 7-8 minutes, until browned and onions are translucent.

Stir in chopped bell peppers, tomato sauce, diced tomatoes, beef broth, water, and brown sugar. Bring to a boil, then reduce heat and simmer for 20 minutes.

Add instant rice and cook uncovered for 5-10 minutes, adding more broth or water if needed.

Ladle into bowls and garnish with fresh parsley or Parmesan cheese. Serve hot.
