All the cabbage roll flavors without the rolling. This deconstructed soup is a warm, low calorie Monday dinner that's ready in 30 minutes.
Heat olive oil in a large pot over medium heat. Add diced onion, carrots, celery, and cook for 3 minutes, stirring occasionally until softened.
Add minced garlic and lean ground beef. Increase heat to medium-high. Brown the beef, breaking it up with a spatula, just until no longer pink. Drain excess fat if necessary.
Stir in salt, pepper, oregano, thyme, and uncooked rice. Let flavors infuse for 1 minute, then add crushed tomatoes and low sodium beef broth.
Add chopped cabbage, stirring to combine. Bring the soup to a boil, then reduce heat to a simmer and cover. Cook for 20 minutes, until cabbage is tender and rice is cooked.
Taste and adjust seasonings if needed. Serve hot, ensuring each bowl gets a generous mix of vegetables, beef, and broth.
